Brain Freeze

You target one creature whose prescience you are a where of and blast it it with a jolt off mind numbing psychic energy. The target creature must make an Intelligence saving throw against your spell save DC. On a failed save the creature takes 1d4 psychic damage and is stunned until the start of its next turn. On a successful save the creature only takes half damage and is not stunned. This spell has no effect on creatures with an Intelligence of 3 or lower.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), an 17th level (4d4).
