Prerequisite: Dex 13+, Wis 13+, Improved Unarmed Strike, base attack bonus +8 or higher.
Required for: Extra Stunning Attacks.
Specifics: A character with this feat can attempt a disabling strike with a -4 attack penalty and a -4 damage penalty. If successful, the target must succeed at a Fortitude save (DC 10 + 1/2 the attacker's level + the attacker's Wisdom modifier) or be held for one round. This attack may be used once per day for every four levels of the character.
Use: Selected. Monks receive this feat for free at 1st level, even if they do not meet the prerequisites. As well, monks suffer no attack or damage penalties when using this feat and may use it once per day per level. Constructs and undead are immune to this attack, as are any creatures that are immune to critical hits.
