Boil

Boils start as small red spheres that slowly grow to full size. When at their full size, they can spurt out a cluster of blood shots at Isaac, similar to one of Monstro's attacks. Boils decrease in size when hit, but will regenerate to their full size until fully destroyed.

• While regular Boils can be touched without taking damage, champion forms do inflict one heart of damage on touch (like all champions).
• Champion Boils grow significantly slower but take more hits to deflate. The exception to this is gray champions, which grow faster and take fewer hits to deflate.

• Gushes were added in Booster Pack #4, after the initial release of the DLC.
• A pustule is the scientific name for a pimple.
• Pustules in Antibirth would burst into Small Maggots as puddles of Green Creep as opposed to the Bloodfly and Red Creep in Repentance. Booster Packs #1
