Attack of Opportunity
Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.

Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

Speed 30 feet
Melee Fist +37 (agile, finesse, nonlethal, unarmed), Damage 3d6+14 bludgeoning
Double Punch (flourish)

Lord Guirden makes two fist Strikes, ignoring the multiple attack penalty until after both Strikes.

Hurl (flourish)
Requirements Lord Guirden has a Medium or smaller creature grabbed

Effect Lord Guirden hurls the grabbed creature into a target adjacent to him. He makes a fist Strike against the adjacent target. On a success, the target and hurled creature both take 3d10+14 bludgeoning damage and are knocked prone. On a failure, only the thrown creature takes the damage and is knocked prone.
Master Brawler

Whenever Lord Guirden makes a fist Strike and hits, he can choose to apply either the Grab, Knockdown, or Push ability to his attack.
