I was wondering this, just now. If you take Weapon Supremacy and get all of those fancy bonuses to, say, a short sword, and then you dual-weild short swords... Do the fancy bonuses stack, or do you only apply them once, no matter how many short swords you use?

It only says that you get the bonuses when weilding your weapon of choice, and that you can't take the feat for more than one type of weapon. But I don't see anything that says you can't use two of your prefered weapon.

Something tells me, though, that they don't stack. What do you guys think?

Actually, the pattern generally is that in the case of something like this, they would stack. Just like with Weapon Specialization or Focus, it doesn't matter if you're single, dual, or sextuple wielding, you still get the bonus unless it specifies that it only works with a single weapon that you're wielding.

Yup. They apply to both weapons. Dont worry tho, its not overpowered. TWF is weak as it is, especially considering the amount of investment it takes to be any kind of good at it. Unless you have sneak attack, in which case, its wonderful
