Constricting Tail
Feats
Whenever Fafnheir hits a creature with his tail, he attempts a grapple maneuver check. On a successful maneuver, the creature is paralyzed. While grappling a creature, Fafnheir cannot move or attack with his tail. Each round as a free action, Fafnheir must make a successful grapple maneuver check or release the grapple. On each successful grapple maneuver check, Fafnheir deals damage to the target equal to his tail attack damage.
