Jedi Lightsaber:
Pay 1 build point, 1 Force -> Equip Equipped Jedi Character or Sith Character unit gets +2 power and "Pay 2 Force -> Deflect 1." Adegan crystals of the Osuss system are ideal for the creation of lightsabers, as they focus the energy released from a lightsaber's power cell into the tight, blade-like beam.
