Anti-Magic Champion (5e Feat)
From D&D Wiki
Years of battling wizards has made you inured to some spell effects.
You gain the following benefits:
- When you are required to make a saving throw against a cantrip or a 1st-level spell, you have advantage on the saving throw.
- When you are subjected to a spell effect that allows you to make a Dexterity 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. You can only use this ability once, you regain the use of this ability after you finish a long rest.
