Vampiric Ward

You choose a creature within range. That creature gains 10 temporary hit points. While it has those hit points, at the end of its turn, if it dealt at least 10 damage to another creature on its turn, it heals 5 hit points. This spell has no effect on constructs.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the creature gains an additional 10 temporary hit points for each slot level above 2nd.
