Don't do it bro, +3 KAS best 1h sword in game (obviously that's subjective, but I think it's a beast with 7 power strike).
I'll tell you, it's an awesome weapon. One of the best for sure.
However, I find I'm not doing as well as I do with my usually weapon types (short blunt/pierce).
To be fair, I only have 5 PS right now, but at 30 I'll have 6. Maybe I'll wait a bit and see how I do...
