Difficulty[edit | edit source]

  • You start the game with only one heart container. This means that without acquiring additional heart containers, dealing any self-damage will instantly kill you.
  • However, with the ability to access all secret rooms, super secret rooms, and crawlspaces on all floors, as well as free access to all the pickups that tinted rocks, vases, mushrooms, skulls, and polyps provide, it is possible for experienced players to get very easy runs.

Strategy[edit | edit source]

  • Epic Fetus Epic FetusEpic Fetus Icon.pngIsaac's tears are replaced with guided missiles, like those used by the Doctor's Remote. is an incredibly powerful offensive item, so you should primarily focus on acquiring health upgrades and defensive items such as Pretty Fly (from a pill or slot machine), Sacrificial Dagger Sacrificial DaggerSacrificial Dagger Icon.pngDagger orbits Isaac, dealing very high damage., Cube of Meat Cube of MeatCube of Meat Icon.pngOrbiting familiar that blocks enemy shots and deals damage to enemies. If collected while already having one, makes the familiar evolve. Only drops from Horsemen. Similar to Ball of Bandages., and Ball of Bandages Ball of BandagesBall of Bandages Icon.pngOrbiting familiar that deals damage to enemies. If collected while already having one, makes the familiar evolve. Only drops from Horsemen. Similar to Cube of Meat.. Demon Baby Demon BabyDemon Baby Icon.pngFollows Isaac and automatically fires at enemies in its reach. and Rotten Baby Rotten BabyRotten Baby Icon.pngA familiar that spawns blue flies. can be helpful as well, as they do not require aiming to deal damage.
  • Pyromaniac PyromaniacPyromaniac Icon.pngIsaac heals 1 heart instead of taking damage from an explosive source. Adds 5 bombs. or 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. are highly useful as they prevent self-damage.
  • Strange Attractor Strange AttractorStrange Attractor Icon.pngPickups, trinkets, and monsters are magnetically attracted to Isaac's tears. is highly effective, because most enemies and some bosses will be pulled towards the missiles instead of targeting the player. However, finding it is extremely unlikely, because it is only found in the Treasure Room item pool.
  • Destroying all rocks and destructibles on every floor, as well as accessing both secret rooms on each floor, is a vital aspect to completing the challenge easily.
  • Loki's Horns Loki's HornsLoki's Horns Icon.pngGives a random chance for projectiles to fire in all 4 cardinal directions. are difficult to utilize effectively with Epic Fetus Epic FetusEpic Fetus Icon.pngIsaac's tears are replaced with guided missiles, like those used by the Doctor's Remote.. However, the extra crosshairs can move through walls, and are always the same distance from the character as the main crosshair, so pretend that they are not there, and just avoid taking damage from the main crosshair.
  • Brimstone BrimstoneBrimstone 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. will make this challenge incredibly easy. It synergizes with Epic Fetus Epic FetusEpic Fetus Icon.pngIsaac's tears are replaced with guided missiles, like those used by the Doctor's Remote., firing 10 blood lasers. If Loki's horns activate, the 40 lasers will usually cover an entire standard size room. With 20/20 20/2020 20 Icon.pngGrants double shot. or the Bookworm transformation, the 80 lasers will destroy most bosses in one shot

Trivia[edit | edit source]

  • A "glass cannon" is a term used for someone or something that deals high damage but can't take much damage.
