Advanced Decay

A pulse of necrotic energy flows from the caster to the target, disturbing the surroundings with a sense of death. If the target is living, they must make a constitution saving throw against your spell save DC. On a failure, the target takes 4D4 necrotic damage, and takes an additional 2D4 necrotic damage at the start of each turn for the duration of the spell. On a success, all damage rolls are halved. When cast at higher levels of the 3rd spell slot or higher, add an additional D4 to each damage roll. When cast on a corpse, the body begins to rapidly decay, and will be entirely reduced to bone over the course of 1 hour. The bones will not be decayed in this manner.
