A. You can buy stance books from an NPC in the starting town. The NPC is located inside the building in the SouthEast side of town.
NOTE : Base level and Stance level requirements may apply to learn a new stance.
you can get books from quests too.

Q. How do I use Dual-Wield stances?
A. First, you must have the stance available, already. If you do, then equip two weapons to your preferred character who will be using a dual-wield stance.
NOTE : Double-Clicking will not equip your second weapon into the second slot. It will only replace your first weapon. To overcome this, click and drag your second weapon into the second slot.
all dual wield stances requires you to learn their skill books first. or else you can't put on 2 weapons.
