Melee Foot +20 (reach 10, unarmed), Damage 2d10+10 bludgeoning

Dual Tusks

The zombie mammoth makes two tusk Strikes, each against a different creature. This counts as one attack for the mammoth's multiple attack penalty, and the penalty doesn't increase until after both attacks.

Impaling Tusks

The zombie mammoth makes a tusk Strike against a creature it's grabbing with its trunk. If the attack hits, the creature is impaled upon one of the mammoth's tusks, freeing the trunk to make attacks. Each of the mammoth's tusks can hold two Medium or smaller creatures. A mammoth can attack with its tusks while creatures are impaled upon them.

Grabbing Trunk

A Medium or smaller creature hit by the zombie mammoth's trunk is Grabbed. If the mammoth moves, it can bring the grabbed creature along with it.
