An umber hulk can deliver blows powerful enough to crush almost any enemy. In addition, its mandibles are strong enough to bite through armor or exoskeletons with ease.
Despite its great bulk, an umber hulk is intelligent. When brute force won't overcome an enemy, it is more than capable of outthinking those who assume it to be a stupid beast. Umber hulks often use their tunneling ability to create deadfalls and pits for the unwary.
Confusing Gaze (Su): Confusion as the spell, 30 feet, caster level 8th, Will DC 15 negates. The save DC is Charisma-based.
