Multiattack

The ape makes one bite attack and two claw attacks.

Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage, and the target must succeed on a DC 14 Constitution saving throw or contract the arcane wasting disease (see sidebar).

Claw

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) slashing damage.

Frenzy (1/Day)

When two or more foes are adjacent to the ape, it can enter a deadly battle frenzy. Instead of using its normal multiattack, a frenzied white ape makes one bite attack and two claw attacks against each enemy within 5 feet of it. Melee attacks against the white ape are made with advantage from the end of that turn until the start of the white ape's next turn.
