You can manipulate the effects of gravity for short distances.

Prerequisites: Wisdom 15+, Speed of Thought, Psionic Charge, Up the Walls, Tempest or zerth cenobite level 6

Benefit: You can use one of your move actions to run across less than solid surfaces including air. This movement can be taken only in a straight line, and it must begin and end on a solid surface. If it doesn't, you fall into whatever you were running across. The maximum increase or decrease in elevation cannot exceed half your movement rate, and this elevation change counts against the total distance of your movement. For example, a psychic warrior with a movement rate of 40 could run at an angle to put her at the top of a 20-foot wall 20 feet away or the bottom of a 20-foot ravine 20 feet away. If you run across a surface that causes damage, such as lava, you are still subject to damage as normal.
