Astereia's Benediction

You point to a creature you can see within range. The target must succeed on a Dexterity saving throw, taking 6d8 Force damage on a failed save, or half as much damage on a successful one. You then restore hit points equal to the spell slot level you used to cast this spell to a creature you can see within 60 feet. 

Using Higher-Level Spell Slots. The damage increases by 1d8 for each spell slot level above 6.
