Hey hey, it’s been a while since I posted, but I hope people will still help me. I just got assassin on RO and I was wondering if anybody knew if the right and left hand masteries up your damage if you’re using katars.
Nope, that’s for double dagger.
all right then. curses! I was hoping it would work for my katars as well. guess I’ll just have to beef up my str after agi then 
thanks Frame-meister
uh…
are you sure framie?
Yep, a katar is a 2-handed weapon, not 2 one handed weapons. My friend and I have already tested it out.
I believe Gravity also confirmed that a while ago. Double Attack, however, does slightly increase Katar damage with the left hand.
