Corpsebloom

The Corpsebloom is a Lunar item introduced in Risk of Rain 2.

Like all Lunar items, the Corpseboom has a powerful effect and a drawback. It increases all healing by 100%, but limits how much you can heal at once to 10% max health. Each bloom increases this amount by 100%, and reduces the maximum healing per second by 50%.

Healing is "stored", so if you heal to maximum life, and then take damage, healing you received earlier may still heal you.
