Morphic Weapon [>] (morph, occult, transmutation) Krekhibrux transforms one of his hands into a tentacle with a blade at the end, allowing him to make morphic weapon Strikes. If he's disguised, whether by magical or mundane means, his disguise immediately ends. He can return his hand to normal with another use of this ability, but doing so doesn't restore his disguise.

Peerless Duplicate (divination, exploration, fortune, occult) If Krekhibrux interacts with a creature for 10 minutes, he can choose to expertly duplicate that person. He can roll any Deception check to Impersonate that person twice and take the higher result. This benefit lasts for 24 hours or until he uses this ability on a different creature.

Serpentfolk Venom (poison) Saving Throw DC 26 Fortitude; Maximum Duration 6 rounds; Stage 1 2d4 poison damage and enfeebled 1 (1 round); Stage 2 3d4 poison damage and enfeebled 2 (1 round)
