evocation cantrip

Casting Time: 1 action
Range: Touch
Components: V, S
Duration: Instantaneous

Finishing the final words of the spell, you real back and punch the target in the head. Make a melee spell attack against the target. On a hit, the target takes 1d8 psychic damage, and the target has disadvantage on Wisdom(perception) and Intelligence(investigation) checks for one round.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
