Also if your left hand has accuracy and attack on it it will apply to both hands, just like 15 dex gets added to the pool of ur dex stat with your gear. the new skill stat will only work for the hand it is equipped on. there have been a few weapons in the past that only worked one way in main hand or woudlnt work at all in the sub slot. I think some of those older TP Bonus items were like that.
