I've added the mexican bandanna as one of the best duel items.
Added the bit about the fort and not being dueled.
Sandals are not one of the "best" items imo. Brown Boots for Range and Fancy Riding Boots for Melee are far better.
The charlatan set isn't that great. The bonuses are good if you have the entire set, but I think it's better to stick with regular dueling gear instead of that set.
brown spiked shoes can be great for resistance duelers, but it's not one of the "best" shoes.
As a resistance dueler myself, I'd pick fancy riding boots over brown spiked shoes anyday.

I'l be adding scenarios for level 50 and level 20 for each duel build's skill distribution, to make it a little easier for lower level players to gauge where they should be.
If anyone has any other ideas as to what else I could add to this guide, it'd be very much appreciated.
