Halo of Flies is a passive item.

Effects

• Spawns two Pretty Flies that block enemy shots.
  • Pretty flies kill some fly enemies upon contact.
  • The orbital limit of three flies cannot be surpassed with this item, reducing its effectiveness if Isaac has two or more orbitals.
• This item belongs to the Beelzebub set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

Notes

• Orbital flies can also be obtained by other means, such as Slot Machines and Pretty Fly pills.
• The following types of flies are instantly killed when they come in contact with the orbitals:
  • Army Fly
  • Attack Fly
  • Dart Fly
  • Fly
  • Hush Fly
  • Moter
  • Pooter
  • Ring Fly
  • Super Pooter
  • Swarm
• Having multiple copies of Halo of Flies, (such as by Diplopia) does not increase the fly cap of 3, unlike The Swarm.

Synergies

• Abyss: When Isaac uses Abyss to absorb Halo of Flies two gray locusts are created dealing half of Isaac’s damage per tick each.

Interactions

• D4: This item can't be rerolled by the D4 or other items that reroll passive items.

Trivia

• This item is used in Solar System (challenge #6).
• This item is a reference to Halo of Flies, by Alice Cooper.
• Halo of Flies was the first orbital item that Edmund McMillen ever implemented into The Binding of Isaac.
• Halo of Flies shares its name with a level from Edmund's previous game Super Meat Boy.
