This unit is used much like starship shields, except that it is character scale. Initial activation requires an Easy melee parry roll, which generates a round shield 50 centimeters in diameter. A character may make a melee parry round — if the roll is higher than the firer's blaster roll (as per normal shield rolls), the wearer has placed the force shield in the way. If the roll is lower than the attacker's blaster roll, the character didn't get the shield in place in time and was hit by the blast. If the defender got the shield in place, the blaster bolt must roll against the shield's defensive field of 4D to see if it penetrates the field (use the protection rules on page 63 of Star Wars, Second Edition). Any further damage affects the target as indicated in the chart "Cover Modifiers." The power cell will work for two minutes before being drained.
