Compost is an activated item added in The Binding of Isaac: Afterbirth †.
Effects[]
- Upon use, converts pickups within the current room to Blue Flies or Blue Spiders.
- Doubles Isaac's current amount of Blue Flies and Spiders.
- If Isaac has no Blue Flies or Spiders, spawns one Blue Fly or Spider.
Notes[]
- The item will cost 10 cents if found in a Shop
- Does not work on Troll Bombs or Mega Troll Bombs.
- One character using it does not seem to double the spiders/flies for other characters. It only seems to double the ones following the character using the item.
Synergies[]
- Book of Virtues: Spawns a wisp in the middle ring if Compost destroys at least one pickup, and the wisp's health will be equal to the number of pickups converted to Blue Flies/Spiders. If Isaac hits the blue fly cap of 64 as a result of using Compost, all but one of Isaac's wisps will despawn.
- Car Battery: Spawns 2 Blue Flies or Blue Spiders for each pickup removed, quadruples the current amount and spawns two if there is none.
- Fish Tail: Isaac will gain twice as many flies per use, meaning each fly will be tripled.
In-game Footage[]
Trivia[]
- Compost is organic matter that has been decomposed and recycled as fertilizer.
