Evoker

When the evoker casts an evocation spell that forces other creatures it can see to make a saving throw, it can choose a number of them equal to 1 + the spell's level. These creatures automatically succeed on their saving throws against the spell. If a successful save means a chosen creature would take half damage from the spell, it instead takes no damage from it.

Melee Weapon Attack +3 to hit, reach 5 ft., one target. 2 (1d6 - 1) Bludgeoning damage, or 3 (1d8 - 1) Bludgeoning damage if used with two hands.
