Amelia's Undead Renewal

You pump necromantic energy into a piece of undead flesh, growing it and allowing you to shape it to fill in the wounds of an undead creature. An undead creature you touch regains a number of hit points equal to 1d8 + your spellcasting ability modifier. This spell has no effect on constructs or living creatures.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d8 for each slot level above 1st.
