Angry Fly

Angry Fly is an unlockable passive item added in The Binding of Isaac: Afterbirth †.

Effects

 * Spawns a fly familiar that orbits around a random enemy and deals 2 damage per tick/30 damage per second to enemies it comes in contact with.
 * It will occasionally make a lunge towards the enemy it is orbiting, allowing brief contact even with smaller enemies.
 * If the enemy it is orbiting dies, it starts orbiting a different enemy.
 * If there are no enemies, it orbits Isaac.

Trivia

 * Angry Fly was added in Booster Pack, after the initial release of the DLC.
 * Angry Fly is based on this Steam Workshop item by Custom Phase.
 * Angry Fly behaves similarly to Level 2 Fly and may be a smaller version of Full Fly, as they both share similar shapes and colors.
