This weapon looks worn and its blade has ruddy tinge, as though it has been stained with blood. Four blood-red rubies surround the weapon’s bronze pommel.

When you score a critical hit against a living creature with an enervating weapon, the weapon bestows one negative level on the target.
Assuming the subject survives, it regains lost levels after 1 hour. Usually, negative levels have a chance of permanently draining a victim’s levels, but the negative levels from the enervating property don’t last long enough to do so.

Prerequisites: Craft Magic Arms and Armor, enervation.
Cost to Create: 4,000 gp (plus 300 gp for base item), 320 XP, 8 days.
