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.

Plunder Life (aura, divine)

60 feet. When a healing effect restores Hit Points to a non-fiend creature in the aura, the amount of Hit Points restored is halved. The rhevanna gains temporary Hit Points equal to the amount of Hit Points restored.

The rhevanna loses any remaining temporary Hit Points after 1 minute.
