As you call out words of dismay, you select a creature in range. That creature gains protection against a single spell or ability. If the creature receives half damage on a successful save of a spell of 2nd level or lower or an ability with a save DC of 12 or lower, the spell has no effect. If the creature fails a saving throw against such a spell or effect, instead treat the creature as if it had succeed. If the a saving throw does not reduce damage from the spell or effect, this spell has no effect.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the level of the spell or DC of the effect that can be targeted increases by 1 for each slot level above 3rd.
