Sounds cool and innovative. Keep up the good work! Will it be for GM mode?
I would love to try it out in my campaign, for NPCs to begin with.

Is it going to be balanced or is it supposed to be a bit OP?

And, if I could make a wish, I would like some slim light two handed swords to go with it (like Katanas). Or maybe GM mode has such swords already? (I havent looked through them all).
