Touch of Idiocy

Standard Action | V, S | Touch | Creature
10 Minutes/level | No | Yes
With a touch, you reduce the target's mental faculties. Your successful melee touch attack applies a 1d6 penalty to the target's Intelligence, Wisdom, and Charisma scores (minimum 1). This spell's effect may make it impossible for the target to cast some or all of its spells, if an ability score drops below the minimum required to cast spells of that level.
