Archaic Defender



The Archaic Defender is a two-handed sword that increases defense rating by 15 and armor by 100 when equipped.

This slightly curved blade is of exceptional craftsmanship. The metal bears a light blue tint. The sword's pommel is wrapped with smooth leather straps that wind themselves about the wielder's hands in combat, allowing him to keep a tight and even grip on his weapon.
