Arcane Stitches

You touch a creature's wound causing it to stitch itself close and causing their natural healing to become amplified. The amplified healing regains a number of hit points equal to 1d6 + your spellcasting ability modifier.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d6 for each slot level above 1st.
