Gigas, Abyss

This ebon-skinned monstrosity has a gaping maw with boar-like tusks and a wide nose beneath a furrowed brow that lacks any sort of eyes or visible visual organs. Its corded muscles twist and writhe beneath its smooth, hairless jet hide, giving its frame a gnarled, unbalanced asymmetry. It moves with a loping gait, however, and wears its armor, composed of thick, welded plates, effortlessly.

Planar Empowerment (Su)

While on the plane of the Abyss, an Abyss gigas gains access to blasphemy (DC 24), cloak of chaos (DC 25), and earthquake (DC 25) as spell-like abilities, each usable once per day. If the gigas ventures onto another plane, it cannot make use of these abilities (though its other spell-like abilities remain available). The save DC for the spell-like abilities is Charisma-based and includes a +5 racial bonus.

Wrenching Spasms (Su)

When an Abyss gigas hits an opponent with its bite attack, the opponent must make a DC 29 Fort save or be overcome by wrenching spasms that wrack its body. These spasms cause the victim to be nauseated and deal 1d6 points of damage to Strength and Dexterity due to the painful contortion of bones, muscles, and limbs. The spasms continue for 1d6 hours or until healed with heal, regenerate, or greater restoration. The effects of this ability do not stack, but once a creature has recovered from or been cured of the effect, it can be affected again. Once a creature has made a successful saving throw against this effect, it cannot be affected by the wrenching spasms from that particular gigas for 24 hours. The save DC is Constitution-based.
