With a word, you coat a creature in a shimmering shield that absorbs the energy of incoming blows. The creature gains 15 temporary hit points the instant before it takes the triggering damage. These hit points last until the start of the creature’s next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you may choose to either increase the range of the spell by 30 feet or increase the number of temporary hit points gained by 5, for each slot level above 2nd.
