Dark Bum is a passive item.

Effects

• Spawns a familiar that follows Isaac around and collects Red Hearts. For every one-and-a-half Red Hearts collected, Dark Bum will generate one of the following:
  • A single Soul Heart. This is the most common effect.
  • A hostile Spider.
  • A friendly Blue Spider.
  • A single Black Heart. This is the least common effect.
• This item belongs to the Super Bum set. Collecting three items from this set will transform Isaac's bums into Super Bum.

Notes

• If Dark Bum enters a Super Secret Room that mimics The Womb, Cathedral, or Dark Room / Library, he will drop Red Hearts, Eternal Hearts, or Black Hearts respectively instead of Soul Hearts.
  • If the Super Secret Room mimics The Womb, he will drop Red Hearts instead of Soul Hearts, then gobble them back up. This can be avoided by allowing Dark Bum to pick up all of the Red Hearts and then quickly exiting the super secret room before he starts dropping hearts. This way, he will drop Soul Hearts.
• Dark Bum will not pick up Gold Hearts, Blended Hearts, or Bone Hearts.
• Very beneficial for ???, since he has no use for Red Hearts.

Synergies

• Little C.H.A.D.: Each Half Red Heart dropped by Little C.H.A.D. can be collected by Dark Bum, increasing the amount of pickups dropped.

Interactions

• BFFS!: No effect, but familiar is bigger.

History

• v1.02: Dark Bum's Red to Soul Heart conversion rate was set to 1.5:1.
• v1.031: Dark Bum was changed to have a chance to spawn friendly Blue Spiders or hostile Spiders.
