Bob's Brain is a passive item.

Effects

  • Spawns a familiar that can be fired towards enemies as a projectile.
    • Removed in Afterbirth Bob's Brain is fired directly from where Isaac is standing.
    • Added in Afterbirth: Bob's Brain is fired directly from where it is located in the chain of familiars behind Isaac, making aiming it slightly more difficult.
  • If it hits an enemy, it deals 3.5 damage and explodes, further damaging and poisoning monsters.
    • The explosion deals 60 damage and the poison deals double Isaac's damage over time.
  • The explosion can hurt Isaac, dealing a full heart of damage.
    • This can make picking up the item a risky choice, as Bob's Brain will always fire, regardless of whether or not Isaac will be caught in the explosion.
  • Once it explodes, it takes a few seconds to re-appear.

Notes

  • Bob's Brain is affected by most bomb modifiers.
  • Bob's Brain only explodes when hitting an enemy, and does not explode upon hitting a fire, poop, or wall. It can destroy poop like normal shots, however.
  • Bob's Brain never launches immediately upon entering a room unless a tear-firing key is released and pressed again, or until several seconds have passed.
  • It is possible to get multiple Bob's Brains to spawn on the same floor by finding one in a golden chest and not taking it
    • Only one copy of the brains will be active at a given time, with another one firing immediately after the first has exploded or starts to return from a miss.
    • Removed in Afterbirth Multiple copies of Bob's Brain will float in the same spot in the familiar line.
    • Added in Afterbirth Each copy takes up their own spot on the familiar line, but only the first one launches out. Respawning brains may end up stacking on top of each other.
