The Lost (Strategy)

From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search

The Lost has no health, dying by any damage taken. Therefore, he needs to be played with extreme care. Although possible, it is extremely difficult to finish a full playthrough without getting hit at all. Powerful item combinations are often necessary for a successful run.

General Tips[edit | edit source]

  • Before attempting runs with The Lost, unlock any items that may be helpful for The Lost.
  • It is recommended to have advanced knowledge of all types of rooms, champions and enemies.
  • The Lost's ability to fly can be used to hide safely above obstacles and pits, avoiding enemies and projectile contact.
  • Always play on hard mode, as hard mode is required to unlock Godhead GodheadGodhead Icon.pngIncreases damage and range while reducing tears and shot speed. Grants homing tears and tears gain a damaging halo.. If the player manages to get good item combinations, the difficulty will not matter much.
  • Bombs can be used to escape rooms you think you cannot handle.
  • The Lost will absorb Soul, Black and Eternal Hearts by picking them up, but will not gain any health from them. It is recommended to avoid picking them up in case the D20, a Dice Room (with 3 pips, 2 if the hearts spawn in the Dice Room), or a Added in  Afterbirth Dice Shard is found later on.
    • The same applies for useless items (except while holding the D4, that can reroll the passive items). If any option to reroll items is found, they can be changed if not yet picked up.
  • Three orbitals of any kind absorb nearly all projectiles. It is recommended to use Slot Machines as much as possible to obtain Pretty Flies.
  • The Lost does not receive Bad Trip or Health Down pills. This makes pills more useful since they are more likely to have positive effects.
  • Added in  Afterbirth With the Missing Poster, a run may be taken to the end with an easier character and finished as The Lost by dying on purpose, granting the unlock for The Lost without doing a full run.
  • Added in  Afterbirth Since The Lost does not take damage from the Greed Mode button, you can dramatically limit the number of enemies you have to face at a given time by stepping back onto the button after activating it.

"The Still Statue"[edit | edit source]

This strategy is very safe and easily played. It combines Gnawed Leaf Gnawed LeafGnawed Leaf Icon.pngAfter standing still and not shooting for a short time, Isaac turns invincible until he moves or shoots. with any automatically damaging Familiar. This allows The Lost to enter a room, become invulnerable, and let his familiar clear the room. There are almost no rooms where The Lost gets hit before he enters statue form. This strategy requires a lot of patience.

Although many familiars are not able to clear all types of enemies or rooms, it is still recommended to get any type of familiar the player finds. Some examples are:

  • Added in Afterbirth †7 Seals 7 Seals7 Seals Icon.pngGrants a random Harbinger familiar that changes every 10 seconds.: Extremely powerful, as the harbringers will travel anywhere across a room spawning locusts and leaving trails of creep. The War and Death harbringers will also chase enemies.
  • Daddy Longlegs Daddy LonglegsDaddy Longlegs Rebirth Icon.pngDaddy Long Legs' shadow follows Isaac and stomps on enemies.: Extremely powerful, because it reaches any enemy and will eventually clear the room against any type of hostiles.
  • Demon Baby Demon BabyDemon Baby Rebirth Icon.pngFollows Isaac and automatically fires at enemies in its reach. and Gemini GeminiGemini (Item) Rebirth Icon.pngSuture becomes attached to Isaac, and does touch damage to enemies within its attacking range. - Reliably take out enemies nearby, but will not target foes far away.
  • Orbitals provide decent damage against chasing enemies, but are useless against enemies that stay on distance.
  • Leech LeechLeech Icon.pngSpawns a friendly familiar leech on the ground that hunts down enemies and heals you for half a heart each time it eats one.: Can chase after enemies like Lil Haunt, but due to its poor programming, it often gets stuck, causing you to have to move to kill an enemy. It is also unable to pass over pits.
  • Lil Haunt Lil HauntLil Haunt Icon.pngA familiar that damages enemies by chasing them as well as inducing the fear effect.: While not as powerful as Daddy Longlegs, it's one of the few familiars that chase enemies (and don't require you to take damage to summon).
  • Midas' Touch Midas' TouchMidas' Touch Icon.pngEnemies that touch you are stunned and turn gold. Any enemy killed while in this state will drop a coin.: Still dealing damages when Gnawed Leaf Gnawed LeafGnawed Leaf Icon.pngAfter standing still and not shooting for a short time, Isaac turns invincible until he moves or shoots. is active, may be useless against bosses who stay away from The Lost.
  • The Peeper The PeeperThe Peeper Rebirth Icon.pngSpawns a familiar that floats slowly around the room on a zig-zag pattern similar to Boom Flies damaging enemies it passes through.: It reaches any spot of a room and will be able to take out most enemies. A lot of time is required, though.
  • Robo-Baby 2.0 Robo-Baby 2.0Robo-Baby 2.0 Rebirth Icon.pngFires lasers at any enemy in its line of sight and moves based on the direction Isaac is firing tears.: Shoots only horizontal and vertical, not reaching enemies that stay diagonally. Robo-Baby 2.0 will still clear most rooms. If Robo-Baby 2.0 is moved, statue form will be exited.
  • Rotten Baby Rotten BabyRotten Baby Icon.pngA familiar that spawns blue flies. and Sissy Longlegs Sissy LonglegsSissy Longlegs Icon.pngWanders about the room, occasionally spawning blue spiders.: Blue Flies and Spiders target most enemies inside a room. The flies may not attack foes far away, the spiders are unable to pass over pits.
  • Added in  AfterbirthSuccubus SuccubusSuccubus Icon.pngSpawns a flying familiar that bounces around the room with a black aura, dealing rapid damage to any enemies inside it. While standing in the aura, Isaac gains a 1.5x tear damage multiplier.: Similar to The Peeper, but with a much larger area of effect. Still has trouble with large rooms, however.
  • The Virus The VirusThe Virus Icon.pngInflicts poison to enemies who make contact with Isaac. Speed down.: Similar to Midas' Touch, enemies that touch The Lost when Gnawed Leaf Gnawed LeafGnawed Leaf Icon.pngAfter standing still and not shooting for a short time, Isaac turns invincible until he moves or shoots. is active will be poisoned, but is useless against foes and bosses who stay away from The Lost.

Issues[edit | edit source]

Although the strategy is quite safe, it is likely that game-ending issues occur. Some example scenarios are:

  • The Lost fights Loki with a Poky inside the room. The boss will always stay at distance, making familiars like Distant Admiration Distant AdmirationDistant Admiration Rebirth Icon.pngA red attack fly circles further out than the Halo of Flies / Pretty Flies, but closer than Forever Alone. Deals more damage than Forever Alone. useless. Poky pushes constantly against The Lost, forcing him not to move.
  • The Lost fights a room full of Mask + Heart, the Hearts being behind a pit. Familiars like Leech are useless, while The Lost is constantly attacked by a Mask.
  • The Lost fights Globins, while his follower is not doing enough damage to finish them off after they fell into goo. One Globin is always alive at a time and attacking The Lost.

It is required to have an emergency option, if a room cannot be cleared as intended in such scenarios. Spacebar Items, Cards and Pills can be safely activated, even if The Lost in statue form currently has enemy contact.[citation needed] Another option is to exit the run and reenter it by pressing the continue button. This will place the player at the start of the room but all monsters killed would have to be killed again if the player did not clear the room first.

Boss Rush[edit | edit source]

The method may be perfect for the Boss Rush fight itself, however the player will probably be progressing too slow, not finishing Mom in time. Therefore this method is not recommended to attain the Boss Rush.

Execution[edit | edit source]

The game is restarted until Gnawed Leaf Gnawed LeafGnawed Leaf Icon.pngAfter standing still and not shooting for a short time, Isaac turns invincible until he moves or shoots. is found in a treasure room adjacent to spawn. Then, the player has to rely on finding proper familiars later on.

"Getting Carried"[edit | edit source]

This strategy is very general, though leading often to success. The goal is to gain a massive offensive potential, killing enemies before they are able to hurt The Lost. To survive game ending mistakes, The Lost also tries to find shielding, invulnerability or reviving items. The strategy bases a lot on item luck, because some of the most powerful items in the game need to be found early on.

Key Items[edit | edit source]

Offensive

  • Brimstone BrimstoneBrimstone Rebirth Icon.pngTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.: Grants massive power, is piercing and spectral, can be charged in the preceding room and instantly fired.
  • Added in  AfterbirthGlass Cannon Glass CannonGlass Cannon Afterbirth Icon.png4 secondsWhen used, reduces Isaac's health to half a heart (including soul and black hearts) and fires one large piercing spectral tear that does a lot of damage. The damage done by Glass Cannon scales with Isaac's damage (at base damage it does 45 damage).: Shoots a giant damaging tear with no downside.
  • Mom's Knife Mom's KnifeMom's Knife Rebirth Icon.pngIsaac's tears are replaced by a knife that pierces enemies, can travel through obstacles, and can hurt enemies while Isaac is holding it. Holding down the fire button before firing increases its range and power.: Offers massive damage, is piercing and spectral.
  • Polyphemus PolyphemusPolyphemus Rebirth Icon.pngMakes Isaac shoot one huge tear. Also reduces Tears to minimum. Damage increased . If tear does more damage than an enemy's life, the tear continues to travel with the extra remaining damage. Increases tear damage more than most other items. If combined with other damage increasing items, it makes most enemies in the first chapters one-shot and shortens boss fights significantly.
  • The Guppy transformation increases the Lost's offensive potential significantly, and several of the items required for it are useful to the Lost in their own rights.

Defensive

  • Dead Cat Dead CatDead Cat Icon.pngSets the amount of red heart containers to 1, but gives Isaac 9 extra lives. After dying, Isaac is teleported to the last safe room. New heart containers can be obtained after picking up this item, but after each death, the number of heart containers is set to 1 again.: Gives The Lost nine lives.
  • Holy Mantle Holy MantleHoly Mantle Icon.pngAutomatically negates first taken damage in every room.: Absorbs the first hit in each room, nullifying a game ending mistake once per room. It also allows the Lost to enter Curse Rooms and open Spiked Chests and Mimics.
    • Care must still be taken when making use of curse rooms, as any damage taken inside of it will nullify the Holy Mantle charge, trapping the Lost inside unless he has some way to generate a shield, teleport out, or extra lives.
    • Added in  AfterbirthThe Holy Mantle as a starting item can be unlocked by by donating 879 coins to the Greed Machine.
  • Added in  AfterbirthHost Hat Host HatHost Hat Icon.pngA host familiar that sits on Isaac's head and has a random chance to block enemy shots and retaliate with 3 tears. Grants immunity to explosions., Infamy InfamyInfamy Icon.pngChance to block projectiles coming from any direction., and Added in Afterbirth †Metal Plate Metal PlateMetal Plate Icon.pngAdds a chance to reflect enemy shots. Grants one soul heart.: Have a chance of deflecting projectiles that come into contact with the Lost.
    • In addition Added in  AfterbirthHost Hat Host HatHost Hat Icon.pngA host familiar that sits on Isaac's head and has a random chance to block enemy shots and retaliate with 3 tears. Grants immunity to explosions. will also make the Lost immune to explosions and stomp attacks, increasing his survivability further and allowing safer use of items like Ipecac IpecacIpecac Icon.pngReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth. and Dr. Fetus Dr. FetusDr. Fetus Icon.pngTears are replaced by bombs that benefit from bomb-enhancing effects and slide for a fixed time after being fired..
  • Lost Contact Lost ContactLost Contact Icon.pngEvery tear has a small shield which will allow it to block one enemy projectile. Destroys bullets upon contact with tears. It makes "bullet-hell" boss fights like It Lives significantly easier.

The goal is to obtain at least one offensive and one defensive item early in the run, additional ones later on. If they are combined with further helpful items, a run becomes very promising.

Note: Godhead GodheadGodhead Icon.pngIncreases damage and range while reducing tears and shot speed. Grants homing tears and tears gain a damaging halo. and Sacred Heart Sacred HeartSacred Heart Icon.pngIncreases damage and range while reducing shot speed and grants homing tears. Grants a Heart Container and replenishes all Red Hearts. are also major offensive key items. However, it is assumed the player has not yet unlocked Godhead. Sacred Heart can earliest be found in the third floor with very low chances, is therefore not mentioned.

Issues[edit | edit source]

  • Although you can restart a game until you find a key item in the first treasure room, you are still dependent on item luck later in the run.
  • Many key items are special items, lowering the chances of finding such combinations.
  • Running only with key items may not be enough, therefore additional damage ups or emergency options may be necessary.

Boss Rush[edit | edit source]

This method is well suited for the Boss Rush, because The Lost is able to progress quite fast with his massive damage output. The Boss Rush fight itself shall be done with extreme care, because many defensive Items lose most of their value in a long fight:

  • Dead Cat Dead CatDead Cat Icon.pngSets the amount of red heart containers to 1, but gives Isaac 9 extra lives. After dying, Isaac is teleported to the last safe room. New heart containers can be obtained after picking up this item, but after each death, the number of heart containers is set to 1 again. would revive you outside, ruining the attempt.
  • Holy Mantle Holy MantleHoly Mantle Icon.pngAutomatically negates first taken damage in every room. will still trigger once in the Boss Rush fight, but that may not be enough for the whole duration of the fight.

Execution[edit | edit source]

The game is restarted until one of the key items is found in a Treasure Room adjacent to spawn. Afterwards, the player has to rely on finding additional key items and synergies later on.
Note that Brimstone can only be found in Devil Rooms, and Dead Cat only in Curse Rooms, Devil Rooms and Red Chests. The player may decide if they want to check on these opportunities or rather restart instantly.
Some players enter a Curse Room if it is located adjacent to the start. Removed in Afterbirth This will usually be fatal. Rarely, though, a Dead Cat can be found in it. This behavior can make sense, as the run would anyway have gotten restarted without a Treasure Room next to the spawn.

"Remote Control"[edit | edit source]

This method bases around any remotely controlled damage source, such as The Ludovico Technique The Ludovico TechniqueThe Ludovico Technique Icon.pngInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy., ???'s Only Friend ???'s Only FriendBlue Baby's Only Friend Icon.pngSummons a big attack fly that can be controlled with the shooting direction-keys., or Robo-Baby 2.0 Robo-Baby 2.0Robo-Baby 2.0 Rebirth Icon.pngFires lasers at any enemy in its line of sight and moves based on the direction Isaac is firing tears.. After entering a room, The Lost tries to find a safe hiding spot as soon as possible, like above an obstacle. After being safe, he uses his remote damage source to finish the room. Acquiring both The Ludovico Technique The Ludovico TechniqueThe Ludovico Technique Icon.pngInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy. and Lost Contact Lost ContactLost Contact Icon.pngEvery tear has a small shield which will allow it to block one enemy projectile. can help immensely, especially during the fights against Isaac and ???, as the tear can easily block all enemy shots. Acquiring The Ludovico Technique and Strange Attractor Strange AttractorStrange Attractor Rebirth Icon.pngPickups, trinkets, and monsters are magnetically attracted to Isaac's tears. can also be very helpful as enemies can be pulled away from The Lost.

Issues[edit | edit source]

  • Many rooms do not contain any safe spot, quickly making the method counterproductive.
  • Flying enemies can reach any spot in the room. Jumping enemies like Hoppers can also jump over obstacles if they find a landing spot behind.
  • The Ludovico Technique The Ludovico TechniqueThe Ludovico Technique Icon.pngInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy. prevents The Lost from firing normal tears, which may be fatal in rooms without hiding places.
  • The player may focus on their controlled tear/familiar, rather than watching The Lost, overlooking a deadly danger.

Boss Rush[edit | edit source]

If the player manages to reach the Boss Rush room, their odds are quite good. The Boss Rush room offers some rocks as hiding spots, and many bosses stay quite calm. This allows for a nice damage output with the remotely controlled familiars. Flying, fast or mobile bosses, like Fistula, may still become problematic, and therefore treated with extreme care. Also the variety of Brimstone and explosive attacks are very dangerous. There is a bug who will give the player the "Boss rush completed" achievement and will unlock the D100 without actually completing the boss rush. In order to make this, the player need some bombs before entering the boss rush. Once the player is inside, he should place bombs in all the skulls he can find, until an enemy spawns from one of them. If the player kills the enemy (Without picking up any of the boss rush items) the game will think the room is "cleared" and give the player the achievement.

Execution[edit | edit source]

The game is restarted until one of the above items is found in a Treasure Room adjacent to spawn.

Emergency options[edit | edit source]

The Lost should always be prepared for the unexpected by having an emergency option.
Note: 9 Volt 9 Volt9 Volt Icon.pngReduces the charge of any Activated Items by 1. Any 1 charge items instead have timed recharges. and The Battery The BatteryThe Battery Icon.pngActivated Items can be "overcharged" to allow for an additional use. allow a much more flexible use of spacebar items and are generally recommended.

Shield and invulnerability[edit | edit source]

Becoming invulnerable is often avoiding deadly situations, therefore having such a card or spacebar item is highly recommended.

  • Rune Of Algiz offers a shield for 30 seconds. Combined with the Blank Card Blank CardBlank Card Icon.png4 roomsHas the same effect as the card or rune currently held by Isaac., it forms one of the best defensive item combinations.
  • Book of Shadows Book of ShadowsBook of Shadows Icon.png3 roomsUpon use, creates a protective shield nullifying all types of damage for 10 seconds. offers a shield for 10 seconds.
  • The Gamekid The GamekidThe Gamekid Icon.png6 roomsUpon use, turns the character into a into a Pac-Man-like creature for 5 seconds, granting invulnerability, inflicting fear on all enemies, and replenishing half a red heart container for every two enemies killed. fears all enemies, deals contact damage and offers invulnerability for five seconds.
  • My Little Unicorn My Little UnicornMy Little Unicorn Icon.png6 roomsUpon use, grants invulnerability and increased speed for five seconds, removing the ability to shoot tears and replacing it with the ability to deal contact damage to enemies. and VII - The Chariot grant invulnerability and contact damage for five seconds. Taurus has a similar effect, but is not completely controllable.
  • Unicorn Stump Unicorn StumpUnicorn Stump Icon.png1 roomsUpon use, grants invulnerability and increased speed for five seconds, but removes the ability to shoot tears. grants a 5 second invulnerability, letting The Lost reposition himself safely. It comes with only one charge, thus can be used often.

Teleport[edit | edit source]

Teleportation can be used to avoid run-ending situations by just leaving the room on demand. However, depending on the method used and on the floor the item is used, the player may end up in a random, even more dangerous room. Teleporting into a Curse Room can potentially end a run, as under normal conditions they cannot be exited without taking damage. There is also a chance of landing in the I AM ERROR room, which forces the player to leave items and pickups behind and potentially forces the player to skip an unlock.

Hard Removal[edit | edit source]

Hard Removal describes the option to clear a dangerous room instantaneously on demand. Items offering hard removal are:

  • Chaos Card kills any enemy in its path, including bosses, in one hit. It is very useful for single-targets, but doesn't have the area of effect for massive enemy horde rooms.
  • Flush! Flush!Flush! Icon.png6 roomsChanges all enemies in the room into poop. Does not work on all enemies (Knights and bosses are immune). Instantly kills Dingle, Dangle, and Brownie. clears a room instantly, but doesn't work against bosses, except Added in  AfterbirthBrownie, Dingle and Added in  AfterbirthDangle.
  • Head of Krampus Head of KrampusHead of Krampus Icon.png6 roomsFires a cross-patterned brimstone shot, just like The Fallen and Krampus shoot. deals massive damage in a cross-pattern, killing all non-boss enemies in its path, and severely damaging bosses.
  • Magic Fingers Magic FingersMagic Fingers Icon.pngUnlimitedFor 1 coin, damages all enemies in the room. can clear a whole room extremely fast if the item is spammed, damage is high enough and if enough coins are available.
  • The Necronomicon The NecronomiconThe Necronomicon Icon.png6 roomsDamages all enemies in the room significantly. and XIII - Death kill most non-boss enemies in a room.

Resurrection items[edit | edit source]

These items do still work with The Lost, although the life number does not appear on the HUD. They give the player another chance, if a fatal mistake was made.

  • 1up! 1up!1up! Icon.pngGives an extra life. Upon death, you will respawn in the previous room with full health and lose the 1up!. offers one life.
  • Dead Cat Dead CatDead Cat Icon.pngSets the amount of red heart containers to 1, but gives Isaac 9 extra lives. After dying, Isaac is teleported to the last safe room. New heart containers can be obtained after picking up this item, but after each death, the number of heart containers is set to 1 again. offers nine lives.
  • Guppy's Collar Guppy's CollarGuppy's Collar Icon.pngGrants Isaac a permanent 50% chance to respawn with 1/2 of a red heart after death. has a 50% chance of reviving The Lost.
    • When combined with Dead Cat, Guppy's Collar takes priority over it, potentially granting more lives.

Angel & Devil Rooms[edit | edit source]

Devil and Angel Rooms appear quite frequently to The Lost, because he is not allowed to take damage. The Lost can take Devil deals for free. However, Angel Rooms offer some of the most helpful items for The Lost.
It is generally recommended to go for Devil deals, and thus hinder Angel Rooms to appear, though the player is free to pursue Angel Rooms if they find them more attractive. Goat Head Goat HeadGoat Head Rebirth Icon.pngA Devil Room / Angel Room Door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II. is a strong item to obtain early as it will ensure that The Lost can visit a Devil or Angel Room on every floor except for Basement/Cellar I and everything past The Womb/Utero II. Removed in Afterbirth The Book of Belial The Book of BelialThe Book of Belial Icon.png3 roomsUpon use increases damage by 2 for the current room and by a further +50% if the character also has the Blood of the Martyr.
Removed in Afterbirth Guarantees a Devil Room or Angel Room will be open after beating a boss while holding it, or Added in  Afterbirth increases the chance by 12.5%.
fulfills a similar effect, however, another spacebar item may be preferred.

Devil Room[edit | edit source]

Although the Devil Room may only contain Black Hearts or Red Chests that only contain Soul Hearts, Troll Bombs or enemy spiders, it usually has helpful items, though some such as Dark Bum Dark BumDark Bum Rebirth Icon.pngSpawns a familiar that follows Isaac around and collects red hearts. For every one-and-a-half red hearts collected, Dark Bum will generate one soul heart, one hostile Spider or one friendly blue spider. or Razor Blade Razor BladeRazor Blade Icon.pngUnlimitedUpon use, deals one heart of damage to Isaac and grants +1.2 damage for the current room. can be either useless or dangerous. Some of the most valuable are:

  • Brimstone BrimstoneBrimstone Rebirth Icon.pngTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.
  • Mom's Knife Mom's KnifeMom's Knife Rebirth Icon.pngIsaac's tears are replaced by a knife that pierces enemies, can travel through obstacles, and can hurt enemies while Isaac is holding it. Holding down the fire button before firing increases its range and power.
  • Goat Head Goat HeadGoat Head Rebirth Icon.pngA Devil Room / Angel Room Door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II.
  • Whore of Babylon Whore of BabylonWhore of Babylon Rebirth Icon.pngIncreases damage and speed whenever Isaac has half a red heart or less (one red heart for Eve), ignoring any soul or black hearts.
  • Added in  AfterbirthEmpty Vessel Empty VesselEmpty Vessel Icon.pngWhile Isaac has no red hearts, this item grants flight and a random chance to activate an invincibility shield for a few seconds. If Isaac gains any red hearts, these benefits will disappear.
  • All items required for Guppy, especially Dead Cat Dead CatDead Cat Icon.pngSets the amount of red heart containers to 1, but gives Isaac 9 extra lives. After dying, Isaac is teleported to the last safe room. New heart containers can be obtained after picking up this item, but after each death, the number of heart containers is set to 1 again. (Note: Red Chests can also contain Guppy items)
  • Many damage ups
  • Items granting Fear Tears

Angel Room[edit | edit source]

The Angel Room often contains Soul or Eternal Hearts, being useless for the Lost. Many items that can be obtained are of no use, too, such as Prayer Card Prayer CardPrayer Card Icon.png6 roomsGrants an eternal heart per use. or Celtic Cross Celtic CrossCeltic Cross Rebirth Icon.pngGrants a chance to trigger the Book of Shadows effect upon taking damage, creating a shield that nullifies all types of damage for 7 seconds., and some such as Dead Sea Scrolls Dead Sea ScrollsDead Sea Scrolls Icon.png2 roomsTriggers the effect of a random activated item from a list of possible options (not every activated item is included). or Breath of Life Breath of LifeBreath of Life Icon.png6 secondsGrants a brief moment of invincibility when the charge bar hits zero. If spacebar is held for an additional second after hitting zero, Isaac will take damage. can actually be dangerous. However, with luck, one may find a very valuable item, such as:

  • Added in  AfterbirthCircle of Protection Circle of ProtectionCircle of Protection Icon.pngSurrounds Isaac with a large white halo. Once per second, the halo deals Isaac's tear damage to enemies inside it. It may also convert enemy shots entering the halo into friendly purple homing tears.

  • The Red Candle Red CandleRed Candle Icon.png4 secondsThrows a persistent flame that deals high damage and diminishes as it damages enemies or blocks shots.'s properties make it one of the most useful items for defeating the waves of mobs and bosses in Greed Mode.

Notes on item selection

  • Best Bud Best BudBest Bud Rebirth Icon.pngWhen hit, summons a white attack fly similar to Distant Admiration for the current room., Guppy's Paw Guppy's PawGuppy's Paw Icon.pngUnlimitedRemoves one red heart container in exchange for gaining 3 Soul Hearts., and Infestation InfestationInfestation Rebirth Icon.png1-3 blue flies randomly spawn every time Isaac gets hit. are not included because while they do not provide any passive benefit, they do count for transformations.
  • Listed items that generate heart pickups of any kind are useless in most scenarios, but can be converted to other types of pickups if The Lost is holding the D20 or D100.
  • Bloody Lust Bloody LustBloody Lust Icon.pngIncreases damage as Isaac receives damage. Damage increase stays for the whole floor. will increase damage if The Lost has multiple lives.
  • Items that activate a Necronomicon-like effect upon getting hit have a very limited use, as they can deal the last bit of damage needed to kill a boss, or clear a room if The Lost has multiple lives.
  • Rosary RosaryRosary Icon.pngAdds 3 Soul Hearts and increases the chance for The Bible to appear in any item pool. is mostly useless, but not completely, as it raises the chance of finding The Bible.
  • Missing Poster Missing PosterMissing Poster Icon.pngIf Isaac dies in a Sacrifice Room, a puzzle piece will appear on his last will (Added in  Afterbirth and unlocks The Lost). Added in  Afterbirth Revives Isaac as The Lost if unlocked. The Missing Poster then disappears. is no longer useless for the Lost.
  • Added in  Afterbirth Ouija Board, Dead Dove and Spirit of the Night are useless in Afterbirth because The Lost now starts with spectral tears. They are still useful items in Rebirth.
  • Added in  Afterbirth Blind Rage is only useless if the player has not unlocked Holy Mantle as The Lost's starting item.
  • Added in  Afterbirth Items that increase your chances of finding Soul Hearts or Black Hearts gain some use when combined with Immaculate Conception.

Negative items[edit | edit source]

  • Ankh AnkhAnkh Icon.pngUpon death, the player will respawn as ??? with 3 soul hearts., Broken Ankh Broken AnkhBroken Ankh Icon.pngWhen held, Isaac has a chance to be revived as ???. Can occur multiple times in the same run., Judas' Shadow Judas' ShadowJudas' Shadow Icon.pngAdds an extra life; upon death, it respawns Isaac as Black Judas with only two black hearts. and Lazarus' Rags Lazarus' RagsLazarus' Rags Icon.pngUpon dying, resurrect as Revived Lazarus with one heart container and Anemic item. grant extra lives but respawn the The Lost as ???, Black Judas, or Lazarus respectively, which will cause the game to treat them as these characters instead of The Lost. It is suggested to avoid these three items altogether if the player is interested in gaining The Lost exclusive achievements and/or completion marks.
  • Dark Bum Dark BumDark Bum Rebirth Icon.pngSpawns a familiar that follows Isaac around and collects red hearts. For every one-and-a-half red hearts collected, Dark Bum will generate one soul heart, one hostile Spider or one friendly blue spider. no longer maintains its main benefit of providing Soul Hearts as Soul Hearts are now useless. While it may spawn a friendly spider, it is also likely to spawn an enemy spider, which can instantly kill The Lost if the player is not careful.
    • With Added in  AfterbirthImmaculate Conception Immaculate ConceptionImmaculate Conception Icon.pngUpon picking up a certain amount of health, spawn a permanent angelic familiar., Dark Bum will be useful to convert useless Red Hearts to useful Soul Hearts. However, the player must still be careful for enemy spiders.
  • Isaac's Heart Isaac's HeartIsaac's Heart Icon.pngIsaac himself is now immune to all damage, and a heart familiar appears and follows Isaac. If the heart is hurt, Isaac is hurt., while having many useful synergies as well as the added benefit of immunity to Brimstone lasers, makes dodging more difficult in many scenarios, leading many players to take damage when they otherwise would not have. It is also very difficult to avoid a stray laser from an Eye, as The Lost cannot block this shot and protect Isaac's Heart from it. Also, there is a chance it can spawn atop an Eye in the It Lives fight, leading to a very cheap and unavoidable death.
  • Any explosive items, such as Anarchist Cookbook Anarchist CookbookAnarchist Cookbook Icon.png3 roomsSpawns six troll bombs around the room., Added in  AfterbirthCurse of the Tower Curse of the TowerCurse of the Tower Icon.pngCauses Isaac to spawn 6 troll bombs on the floor every time he gets hit, similar to the Anarchist Cookbook mechanic., or Ipecac IpecacIpecac Icon.pngReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth. should be used with extreme care.
    • If the player chooses to pick up Ipecac IpecacIpecac Icon.pngReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth., they should not pick up Loki's Horns Loki's HornsLoki's Horns Icon.pngGives a random chance for projectiles to fire in all 4 cardinal directions. or Mom's Eye Mom's EyeMom's Eye Rebirth Icon.pngAllows Isaac to fire tears from the back of his head., as an unexpected shot against a wall will lead to instant death. Lost Contact Lost ContactLost Contact Icon.pngEvery tear has a small shield which will allow it to block one enemy projectile. is also problematic as it can cause explosions to happen in closer proximity to the player than desired.
  • Items that work by causing self-damage, such as the IV Bag IV BagIV Bag Icon.pngUnlimitedUpon activation, Isaac loses a half-heart (one whole heart in The Womb onwards) for a random amount of coins, similar to the blood donation machine., Blood Rights Blood RightsBlood Rights Icon.pngUnlimitedDamages all enemies in the room, but deals a heart of damage to Isaac with each use. or Razor Blade Razor BladeRazor Blade Icon.pngUnlimitedUpon use, deals one heart of damage to Isaac and grants +1.2 damage for the current room. will end the run if used and must be avoided. Dead Sea Scrolls Dead Sea ScrollsDead Sea Scrolls Icon.png2 roomsTriggers the effect of a random activated item from a list of possible options (not every activated item is included). also has the potential to prematurely end a run if a self-damaging item is triggered. Isaac's Heart Isaac's HeartIsaac's Heart Icon.pngIsaac himself is now immune to all damage, and a heart familiar appears and follows Isaac. If the heart is hurt, Isaac is hurt. will allow The Lost to use these items without taking damage.
  • Bucket of Lard Bucket of LardBucket of Lard Icon.pngGrants two empty heart containers and heals Isaac by half a heart, but decreases speed by 0.2. reduces speed by 0.2 and does not provide any benefit.
  • Leo LeoLeo Icon.pngAllows you to crush rocks when you walk over them. and Thunder Thighs Thunder ThighsThunder Thighs Icon.pngDestroys rocks upon contact with Isaac. Adds one heart container and lowers Speed. are not great as they remove The Lost's ability to use obstacles to his advantage, as they can break these obstacles. Also, stepping on a poisonous mushroom, or carelessly stepping on a bomb rock can end a run. The only benefit is the small chance of finding a trapdoor or items like Dry Baby Dry BabyDry Baby Icon.pngSpawns a familiar that follows Isaac around and blocks enemy projectiles. Upon blocking a shot, it has a chance of triggering The Necronomicon effect. or The Small Rock The Small RockThe Small Rock Icon.pngIncreases damage by 1, increases tears by 0.2, and decreases speed by 0.1. when breaking said obstacles.
  • Strange Attractor Strange AttractorStrange Attractor Rebirth Icon.pngPickups, trinkets, and monsters are magnetically attracted to Isaac's tears.: Unpredictably pulls enemies towards The Lost, especially floating enemies like Boom Flies. It's advised to avoid this item unless The Lost has The Ludovico Technique The Ludovico TechniqueThe Ludovico Technique Icon.pngInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy., as both items combined create a powerful synergy.
