Manslayer of the Qiraji

Manslayer of the Qiraji is a two-handed sword with a generous amount of Strength, Agility and Stamina. This is an appropriate sword for the Warrior class. Paladins also receive a significant benefit from the weapon's stats and speed. While some Hunters may wish to attain the Manslayer, they lack significant benefit from the sword's stat bonus alone.
