When you go to the items list and look under what weapon you are currently equipped, I don't understand two things. First, what does (requires 3 Swordsmanship mean and under that it will say something like "stacked". What does this mean?????? Thanx this forum is helpful!!!!!
(requires 3 Swordsmanship) means that you need at least 3 in swordsmanship to deal the listed damage of that weapon; otherwise you deal very little damage.
(Stacking) means that that particular modifier, like Lengthens Bleeding, will stack with anything else that lengthens bleeding.
If your still confused, remember to hit k and look at your skills list. You have to set your attributes accordingly whenever you level or change your skills. Swordsmanship is a warrior attribute, so if you aren't a warrior primary or secondary you can't meet that weapons requirement.
