You can gain a supernatural ability of a metamorphed form.
Benefit: Each time you change your form, such as through the
metamorphosis power, you gain one of the new form's supernatural abilities, if it has any.
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.
