You can temporarily paralyse an opponent with a hit.
Prerequisite: proficiency with bludgeoning weapon, Stunning Attack, base attack bonus +6.
Benefit: As a full-round action, you can make a single attack roll with a bludgeoning weapon that inflicts normal damage. If the attack succeeds in damaging your opponent, they must make a Fortitude saving throw (DC 10 + your Wisdom bonus + half your base attack bonus) or be paralysed and helpless for one round.
