Murlynd's Rattlesnake Whip

This rattlesnake-skin whip is tipped with the filed-down fangs of several snakes. Murlynd did not fashion this weapon, but rather he discovered it on a distant world desperately in need of heroes that he frequents. The whip is a marvel, but because of the six-shooters and fabulous dancing sword he carries it often goes unnoticed. It has, however, saved Murlynd's life on more than one occasion.
The prehensile whip extends at your command to grasp items, operate levers, or pull door handles. It can even lower you as a rope and pulley, but it also has use as an offensive weapon. This +3 disarming sweeping whip grants you a +2 competence bonus on disarm attempts and a +2 competence bonus on Strength checks made to trip an opponent with it. Opponents cannot disarm you of this weapon. In addition, the whip grants you the ability to grapple any target at a range of 10 feet with a successful grapple check.
