You hit a creature so hard, it sees little birdies or stars around its head… right before you cave it in.
Prerequisites: Slapstick class feature, Weapon Focus (improvised weapons).
Benefit: On a critical hit with an improvised weapon, if the creature fails a Fortitude save (DC 10 + 1/2 your character level + Charisma modifier), it is staggered for a number of rounds equal to your Charisma modifier. A given creature may only be affected by this once per day. If you have at least 8 BAB, there is no imposed limit on times per day.
