Power Through Spells

Through brute strength and/or training, you've managed to learn how to parry spells with your weapon, fists, shield or even with kicks and headbutts. When rolling a saving throw against any spell, you can use your Strength modifier instead of the usual one. Not only that, if you are asked to make a saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

If you already have an ability that reduces spell damage (such as the Rogue's Evasion), you can add your proficency bonus a second time to your roll.
