You’ll also want to invest at least a few points in the Warmonger skill tree to gain access to Taunt. If you’re wanting a tank character, then you’ll definitely want to invest in the Weapon and Shield skill tree. It’s also important to note that you won’t be able to dual-wield weapons. In addition, the Warrior can equip the heaviest of armors plus they have the ability to equip shields that also give an armor bonus. The class itself has access to most weapon types with the exception of staffs and ranged weapons. The Warrior class in Dragon Age 2 can either be a damage dealer or a ‘tank’.
