Up the Walls [Psionic]
Prerequisite: Wis 13+, Speed of Thought, Psionic Charge, reserve power points 5+.
Benefit: The character can take part of one of his or her move actions on a wall if the character begins and end the move on a horizontal surface. The height the character can achieve on the wall is limited only by this movement restriction. If the character does not end his or her move on a horizontal surface, he or she falls prone, taking damage as appropriate for his or her height above the floor. Treat the wall as a normal floor for the purposes of measuring movement. Passing the boundary between horizontal and vertical is equivalent to 5 feet of movement along a normal floor. Opponents on the floor still get attacks of opportunity as the character moves up the wall within areas they threaten.
Special: A character can take other move actions in conjunction with moving on a wall.
