The Dual Wielding skill is generally used by Scoundrel characters who wield one weapon in each hand. This is a new skill introduced in Enhanced Edition, which allows the user to effectively double their damage output at the sacrifice of a defensive option. Dual Wielding can also be used by Wizard classes, who can wield an elemental Wand in each hand. The advantage to this is that many wands provide hefty bonuses to Health Points, increasing survivability by up to 2 Constitution points! This build doesn't have many other perks, though.
