Obtained after the quest Into the Void for 150 commendation points and 50,000 coins, you can upgrade your Korasi's sword into a powerful Tyr's sword, Commodore Tyr's old sword he used when he was a captain. Because of its stats, the Tyr's sword is one of the best one-handed weapons in the game. In addition, the special attack of the sword hits more enemies and now doubles the max hit of the Korasi's sword. Also the higher the combat stats, the more chance of the sword given you a random heal during Pest Control.
