Special Abilities

Chainstorm (Ex)

Chains and flesh tendrils constantly lash at anything that approaches the herald. A creature that enters the area or begins its turn within it takes 1d12 points of bludgeoning and slashing damage. The chains entangle any creature so long as it's in the area (Reflex DC 25 negates). The save DC is Constitution-based.

Exaction (Ex)

The herald is healed of 10 points of damage in any round it deals damage, as if it had fast healing 10.

Howl of Despair (Su)

The Prince in Chains can loose a howl of immortal agony once every 1d4 rounds. All nonevil creatures within 60 feet must succeed at a DC 22 Will saving throw or take 6d6 points of sonic damage. Any within 10 feet who fail their saves are also affected as per the insanity spell. This is a sonic, mind-affecting effect. The save DC is Charisma-based.

Unnerving Gaze (Ex)

A creature that fails its save against the herald's unnerving gaze is staggered for 1 round.

Vicious Critical (Ex)

If the herald confirms a critical hit, the attack also deals 2 points of Constitution damage.

Zon-Kuthon has stripped the flesh from this spirit-wolf and replaced it with haphazard layers of metal, leather, and necrotic tissue to create a terrifying herald.
The Prince in Chains stands 18 feet tall and weighs nearly 3 tons.
