Metamorphic Transfer [Psionic]
You can gain a supernatural ability of a metamorphed form.
You gain only three uses of the metamorphic ability per day, even if the creature into which you metamorph has a higher limit on uses (You are still subject to other restrictions on the use of the ability.) The save DC to resist a supernatural ability gained through Metamorphic Transfer (if it is an attack) is 10 + your Cha modifier + 1/2 your Hit Dice.
You cannot use the supernatural abilities of creatures whose form you assume.
