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; Any healing gets diverted into Corpsebloom's "Healing store" and every 0.2 seconds, Corpsebloom takes from this store and the holder recovers up to 2% of their maximum health (for a total of up to 10% of their maximum health 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

 * The Corpsebloom is best used for short runs, where the player is unlikely to exceed the healing cap by much and the item will effectively act as a Rejuvenation Rack. On long runs where enemies are more plentiful and deal more damage, the Corpsebloom can lead to an untimely death due to delayed healing.
 * should avoid this item in general when using their "plant" skills that cost HP, especially since those skills recover a large amount of health in the first place.
 * Having more than 1 Corpsebloom will make it almost impossible to heal, as the healing cap is halved with every additional Corpsebloom. Rejuvenation Racks will become a necessity to raise the cap again to a reasonable amount.
 * The can synergize with the Corpsebloom, since the Planula will generally not exceed the healing cap by much.
 * The can work surprisingly well with the Corpsebloom.  heals 18.2% of the user's max health total over a 3 second period, so when doubled and capped the user heals 30% of their max health while in Shadowfade and the remaining 6.4% 1 second later.
 * Large amounts of healing can be stored up using while standing still in a safe situation to be used afterwards while moving. This can be useful during waiting periods 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 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.
