Shadowbrand is a Sword exclusive to the Forgotten, received for completing Chapter 3 of their faction quest. It is unlocked simultaneously with Shadowbinder and Ziema Adya's second form, who is equipped with Shadowbrand and Shadowbinder by default. Due to the Shadowstrike capacity, the weapon grants an additional +30% Attack if it is equipped along with Shadowbinder, making it most effective to equip this weapon on Forgotten heroes, who can take advantage of that bonus through the Dual Wield capacity.
Of the two swords that comprise the legendary pair of weapons, Shadowbrand is the cruel twin. Eager to inflict the most painful blows, Forgotten lore claims that if you place your ear near its edge you will hear the screams of its first victims, a Vaulter clan assassinated by Master Shadow Maka Ulum. It is even more dangerous in attack when paired with its twin, Shadowbinder.
