One of our players is not a Jedi and happens to have found a lightsaber lying around in an Imperial Officer's art gallery.
He knows he can't train ranks into it, so he's making the best of it. He wants to wield the lightsaber in his off-hand and continue using his ranged light blaster in his right hand. The plan is to use the lightsaber as a blaster shield, not something so crazy as redirecting the blaster bolts back at his enemies. He wants to gain a rank in the sub-skill of lightsaber deflection, not general lightsaber usage, mind you. He wants to train the same way as Luke did in ANH, with a remote droid training him, maybe with enough training, to actually redirect a few like a Jedi, except with raw skill instead of the force.
How would you go about this player's proposition, if you were GMing for him?
