Brutal Attacks are a stronger form of Tyris Flare's normal attacks. A brutal attack can be told apart from normal attack when Tyris's sword flashes with flames. Successfully executing a brutal attack and hitting an enemy with it will deal more damage and build up the Titan Bonus.
To do a brutal attack press the attack button just as the attack finishes. It can be done repeatedly to attack in brutal combos, allowing the player to quickly defeat enemies.
