Curing Tithe

A creature you touch regains a number of hit points equal to 2d10 + your spellcasting ability modifier, but reduces the maximum hit points of that creature by twice the level of the spell cast until their next long rest, transferring those hit points to you as temporary hit points. This spell has no effect on undead or constructs.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d10 for each slot level above 1st.
