The  is a lunar item in Risk of Rain 2.

All the player's healing is increased by 100% (+100% per stack), but unlike the, regeneration is not increased. Additionally, all healing is applied over time, ticking every 0.2 seconds, at a maximum rate of 10% of the player's max health per second or 2% of their max health per tick. This maximum rate is halved per additional stack.

The healing increase scales linearly while the amount of maximum health that can be healed scales hyperbolically.

Trivia

 * Initially, the Corpsebloom would give the player a 5% critical strike chance and a chance to "critically heal," doubling the amount of HP restored. The chance for this to happen would be determined by, and the player's chance to deal critical damage would be lowered by this amount. This was abandoned before the Early Access release because "[crit heal] wasn't as cool as it sounded". The Corpsebloom still has the internal name 'CritHeal' as a relic from this early development stage. This is not to be confused with 'HealOnCrit', which would be the.
 * The effect of Eclipse 5 is applied twice when calculating the heal for Corpsebloom: once when the initial heal is calculated and again when the delayed heal occurs. This makes a single Corpsebloom a useless pickup on Eclipse 5 and up.
 * In the RoR2 Discord poll of June 10th 2019, the Corpsebloom was voted the least favorite lunar item.
