At 1st level, you can cause a creature to burst out laughing for 1 round as a melee touch attack. A laughing creature can only take a move action but can defend itself normally. Once a creature has been affected by laughing touch, it is immune to its effects for 24 hours. You can use this ability a number of times per day equal to 3 + your Charisma modifier. This is a mind-affecting effect.
