Fiery Touch (Ex): Touching or being touched by a phaethon deals 2d6 points of fire damage.
Fiery Overrun (Ex): A foe who is successfully overrun by a phaethon is treated as if swallowed whole.
Improved Grab (Ex): If the phaethon hits with a pseudopod, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. Phaethons can use improved grab on a Huge or smaller creature. The phaethon has the option to conduct the grapple normally, simply maintaining a pseudopod hold, or attempting to absorb the opponent by swallowing the foe whole. Each successful grapple check it makes during successive rounds automatically deals the damage listed for the pseudopod.
Swallow Whole (Ex): The phaethon can absorb opponents it holds with a second successful grapple check after a grab. The opponent must be Huge or smaller. Absorbed creatures take 20d6 points of fire damage and 10d6 points of bludgeoning damage each round they remain inside a phaethon. Victims must make a successful grapple check to “swim” free of the living magma of the phaethon.
