Actions

Multiattack

The aurumvorax makes one Bite attack and two Claw attacks.

Bite

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage. If the target is a creature wearing armor of any type, the aurumvorax gains one of the following benefits of its choice:

Frenzy

The aurumvorax has advantage on attack rolls until start of its next turn.

Invigorate

The aurumvorax regains 6 (1d8 + 2) hit points.

Claw

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage. If the target is a Large or smaller creature, it is grappled (escape DC 14). Until this grapple ends, the aurumvorax can't use its Claw attack on another target, and when it moves, it can drag the grappled creature with it, without the aurumvorax's speed being halved.
