Sutures

A creature of your choice that you can see within range regains hit points equal to 1d4 + your spellcasting ability modifier. The caster takes the same amount of damage that was healed from the target. On the next turn, the caster may continue to heal the target creature by expanding their bonus action. If this is done the healing effect is doubled, however so is the damage dealt back to the caster. This spell has no effect on constructs.
