Wound

This necromantic spell pours a minute amount of negative energy into the target, accelerating injuries to living tissue and making wounds more serious. Even a small knife wound can be made to bleed more heavily, the flesh around it turning septic as the spell works its dark magic.

Make a ranged spell attack against the target. On a hit, the target will lose one extra hit point every time it takes damage from any source, for the duration of the spell. This spell has no effect on undead, constructs, celestials, and fiends.
