Babylon 5 Electromagnetic Shield

Electromagnetic Shield
Dominant Faction: Vorlon Empire
Effect: All craft attempting to fire on or detect the user of this device suffers a -2D+2 penalty to Fire Control and Sensors dice rolls. In addition, the user of this device suffers a -1D+1 penalty to their own Sensors and Fire Control attempts.
Description: Generally referred to as an EM shield, this field of powerful electromagnetic energy surrounds a vessel, making it difficult to get a proper sensor lock. Like the tension between opposite polar magnets, weapons fire also slows down slightly when it comes into contact with the field.
