Difficulty[edit | edit source]

You start the challenge Blindfolded. You cannot use tears.
Your only means of attacking are Distant Admiration Distant Admiration , Forever Alone Forever Alone , and bombs, while Halo of Flies Halo of Flies provides projectile defense.

Strategy[edit | edit source]

  • Because you start with 3 Fly items, you also gain the Beelzebub bonus. This turns all enemies flies into friendly Blue Flies. On higher levels, you can amass quite a lot of them.
  • Your orbiting attack flies can be quite powerful, especially the red one. This will require maneuvering into position to deal damage, however, and they are constantly moving. Be prepared to tag your enemies and retreat so you don't take damage.
  • Shops can carry BFFS! BFFS! and Hive Mind Hive Mind ; the former affects the damage of your orbiting attack flies and the latter affects the damage of the blue flies spawned from Lord of the Flies. Broken Watch Broken Watch and Stop Watch Stop Watch are good items to buy as well, since they slow enemies down.
  • Obtaining Gnawed Leaf Gnawed Leaf makes the challenge trivial as you can deal damage with orbitals while being invulnerable yourself. Obtaining it is highly unlikely however, since there are no Treasure Rooms present.
  • Obtaining Ball of Bandages Ball of Bandages or Cube of Meat Cube of Meat is helpful as it adds a third close range orbital to protect you from three directions.
  • Avoid any items or dungeon features that shuffle your inventory, such as the D4 D4 , D100 D100 , or Dice Rooms with 1 or 6 pips. It is possible to get stuck with no method of attack if too many of your items reroll into shooting based items. You can also be stuck with methods of attack that require you to put yourself into more danger than the attack flies you start with. You may have no alternative than to abandon your run.
  • Obtaining the Rune of Algiz, Chaos Card Chaos Card or The Bible The Bible can be really handy in killing Mom and Mom's Heart/It Lives!.
  • Devil Room deals such as Brimstone Brimstone , DLC Indicator.png Maw of the Void Maw of the Void , and Mom's Knife Mom's Knife will be ineffective, because of the Blindfolded condition.
  • The Boomerang The Boomerang is a useful purchase from the shop as it has a chance to freeze enemies, allowing you to safely use your attack flies against them for the duration of the freeze.
  • Transcendence Transcendence and other flight items are useless in this challenge, because the Beelzebub transformation grants flight.
  • Obtaining Bob's Brain Bob's Brain can be handy for disposing bosses. If used carefully, its damage and poison effect can make bosses much easier. It also adds the ability to break poop or golden poop to gain health, coins or bombs.
  • DLC Indicator.png Black Powder Black Powder is helpful for damaging non-flying enemies and bosses.
  • DLC Indicator.png Incubus Incubus will make things much easier if it is unlocked.

Unlockable Achievements[edit | edit source]

Trivia[edit | edit source]

  • The challenge is a reference to the Solar System; Isaac represents the sun and the flies represent planets.
