Decompose

You reach out and touch the corpse of a creature. For the duration, the corpse will rapidly decompose, sprouting fungus and moss as it begins to degrade into compost. 1d4 - 1 worth of flowers sprout from the corpse as it decays. Drawing from the life of these flowers you may recover 1hp per flower that sprouts, this effect can only be used once per long rest. The effects of Decompose do not affect the requirements for resurrection, raise dead, etc.

At Higher Levels. At 5th level the amount of flowers that spawns increases to 2d4 - 2 and at 9th level 3d4 - 3.
