From Grand Fantasia Wiki
Dual wielding is wielding two one-handed weapons at the same time. If a weapon has the label "Unique Equipment", it is impossible to wield two of these at the same time.
- Archers (and thus Assassins and Rangers) can automatically dual wield when they reach lvl 16.
- Berserker requires the Moon talent "Dual Blades" to be able to dual wield.
- Sage requires the Moon talent "Woodland Warrior" to be able to dual wield.
