Corpsebloom

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; whenever the player would heal, it is instead stored in the Corpsebloom. Every 0.2 seconds, the Corpsebloom takes from this store and heals the holder up to 2% of their maximum health (up to 10% per second). This healing cap is halved per additional stack.

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

Tips

 * Whether or not to pick up the Corpsebloom basically depends on how much healing the player currently has; if they cannot heal at least 10% of their max health per second, then the Corpsebloom is almost entirely beneficial. If their healing exceeds the cap, or they have large bursts of healing (e.g. from the ), then the Corpsebloom will likely be detrimental.
 * As a result, the Corpsebloom is generally more effective on short runs e.g. going for Mithrix without looping, and typically falls off in effectiveness on long runs, as enemies deal much more damage and thus the player must heal much more.
 * suffers a delay on healing from all abilities while holding Corpsebloom.
 * While holding a and a Corpsebloom, the user heals 30 HP upon taking damage. The Planula is unlikely to exceed the Corpsebloom's healing cap.
 * heals 18.2% of the user's max health total over 3 seconds. While holding and one Corpsebloom,  heals 30% of max health while intangible and the remaining 6.4% of max health 1 second later.
 * Stand still while holding to store healing quickly. This can be useful during waiting periods or between waves of various battles.

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.
 * Similarly to how the Rejuvenation Rack affects the Corpsebloom's healing, the effect of reduces healing twice when calculating the heal for Corpsebloom. This makes even a single Corpsebloom a useless item to pick up on Eclipse 5 and higher.
 * In the RoR2 Discord poll of June 10th 2019, the Corpsebloom was voted the least favorite lunar item.
