A bright yellow beam bursts from your extended fingertips. The beam emits an "uh" sound, like someone trying to think of a word.

This ray clouds the mind of your enemy, damaging its intellect. You must succeed on a ranged touch attack with the ray to strike a target. A subject struck by the ray takes 1d4+1 points of Intelligence damage. If the target is a wizard, she might temporarily lose the ability to cast some or all of her spells if her Intelligence drops too low.

Material Component: A miniature cone-shaped hat.
