SQ mythic, shadow dweller
Chain Lash (Ex) A chain lash functions as a natural attack that deals slashing and piercing damage and has a reach of 10 feet.
Mythic (Su) Zon-Kuthon is treated as a 10th-rank mythic creature for the purposes of any effect that depends on his mythic rank. He has the appropriate amount of mythic power (10/day, surge +1d12) for a creature of this mythic rank.
Shadow Dweller (Ex) As long as he is in an area of complete darkness (including supernatural darkness), Zon Kuthon is considered for all purposes as if he were on his home plane and thus cannot be affected by banishment, dismissal, or other such effects. He loses the benefits of this ability if he is on a strongly good-aligned plane or the plane of positive energy.
Unnerving Gaze (Su) A creature who fails a save against Zon Kuthon's gaze is staggered for 1 round and permanently affected as per crushing despair. The crushing despair effect is a curse effect, and can be removed via remove curse. If a creature is already suffering from this effect, each subsequent failed save against this gaze attack also inflicts 1 negative level.
