What CF might this have for a Star Wars campaign, it basically disables all but a select type of lightsaber for D3+2 minutes (my estimation)
Also if any star wars buffs see this, is there any way to isolate ones self from the effects of the force. My character is an assassin specialising in killing jedis. A cortosis blade means the jedi is defenceless apart from their force skills. If I can make myself immune to all force effects for even a short time, this means they are utterly useless against me.
