Does Advance Sword Mastery and Sword Mastery stack?

Does Advance Sword Mastery and Sword Mastery stack? i read in some post say that they don't stack and some post say they stack.

I think they both should stack cause they're both passive skills right? o.o;

I believe they do stack, but it's wise to not get the sword mastery in first job, and get the advanced one in second job. Partially because the one in first job adds a number and not a percentage, meaning you will always get a fixed damage. It also only effects normal physical attacks, not skills.

tl;dr. Don't get sword mastery first job, get the advanced sword mastery.

Are not sword masteries bugged for warriors and % values do not work.
