The Battle-Brand's abilities include two self-buffs to reduce magical damage taken and reflect a portion of damage taken back to the source. It also features Foebringer, an AoE pull for all nearby enemies, and Bandage, a self-healing spell to keep the Warrior up longer. Last but not least is the ultimate ability, Stoic Defense, which makes the Warrior entirely immune to damage for a short time while consuming mana and stamina. Take a look at the role's abilities in action in a preview video just past the cut.
