Personal Defscreen is one of Rocket Raccoon's abilities from the Galactic Guardian directory, and first becomes available at Level 2. With it, Rocky can spend a large portion of his spirit to establish a defensive force-field that absorbs a significant portion of enemy damage. The field itself has its own 'hit-points', which are depleted by the portion of damage the shield absorbs. The Defscreen field remains in place indefinitely until its points are completely spent; however, the player can trigger this ability again to 'recharge' the shield at any time.
Personal Defscreen's points are also expended to add additional damage to Tactical Destruction.
