Zarothrask's Contract

ITEM 9
Bulk —

You've bargained for power with a gongorinan, but in return, you must avoid furthering demonic goals. You gain a +2 item bonus to Athletics checks to Disarm manufactured items and to Grapple. Once per day, the gongorinan can warp your body with animal features; you must attempt a DC 25 Fortitude save or become Sickened 2. When you recover from the sickened condition, your features revert to normal. The gongorinan will usually do this if you sin or aid a demon, even unintentionally.

Activate—Gongorinan's Emergence (concentrate, mental, morph, occult, unholy)
Frequency once per day

Effect Stony tentacles burst out of your body, lashing at foes. Creatures in a 10-foot emanation take 6d6 bludgeoning plus 2d6 mental damage (DC 25 basic Fortitude save); on a failure, the creature also becomes Sickened 1 (sickened 2 on a critical failure) as parts of their anatomy temporarily warp into animal features. When a creature recovers from the sickened condition, its features revert to normal.
