Your ability requires an All-Out Attack maneuver; you can’t use it with any other maneuver (e.g., Move or Change Posture). You have no active defense while using it. If it would let you move more than a step, you’re limited to half your Move in a forward direction. You may attack if the advantage is one that lets you do so, and receive the benefits of All-Out Attack, but All-Out isn’t just for attack abilities – you can add it to any advantage that requires a maneuver to use (typically Concentrate or Ready), replacing the standard maneuver with All-Out Attack. Explain what you’re doing that limits you: deep concentration, spinning in place, etc.

This new maneuver, first introduced on p. 11 of GURPS Psionic Powers, gives you +1 to all rolls required to perform your ability, but at the cost of your active defenses. You may move only a step. If you are knocked down, injured, or otherwise distracted, you must make a Will-2 roll (the usual Will-3, at +1 for this maneuver) to maintain your concentration. -25%.
