You can tell a joke so bad it hurts. Quite literally.
EXP Cost: 6 EXP
Benefit(s): As a standard action you can make an attack against an enemies' Will Defense (using Attack Bonus, Charisma) and on a successful hit the enemy takes 2d6 points of damage per point in Charisma you have. This only affects creatures able to understand your language, and capable of humor (tasteless or not) and emotions.
