Concealment: Pocket
A phase shield works by shifting the user to hyperspace whenever he is threathened by an attack. This makes the user semi-transparent and intangible.
Each shot in which this shield activates costs the user a single shot from his shot counter. This is not so much because the shield takes time to use as it is because of the disorientation caused by phazing. The shield still works when the user is out of shots.
The shield activates whenever the user would normally have been hit by an attack. When active, the shield improves the user's Dodge by +5. There is no certainty that this will be enough to avoid the attack, but at least it will make it less effective.
