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 20 feet

Melee Fist +12 (reach 10, unarmed), Damage 2d6+5 bludgeoning

Massive Strike

The behemoth makes a melee Strike and, if the attack hits, it can push the creature back 10 feet (20 feet on a critical hit). The target must succeed at a DC 19 Fortitude save or be knocked Prone by this attack.

Stomp

The behemoth can stomp on the ground, causing all creatures within 10 feet to fall Prone (DC 19 Reflex save negates).
