Blade of Valgyr [Major Artifact]

This chaotic evil intelligent blade (Int 16, Wis 10, Cha 16, Ego 20) is a +4 keen, unholy, wounding bastard sword. It can cast detect magic at will and darkness three times per day. It has 10 ranks in Bluff, grants the bearer resistance 10 against fire and cold, and speaks Common, Abyssal, Celestial, and Draconic. The sword is a tainted object and requires the bearer to save against taint each day it remains in her possession. Each day it does not take the life of a lawful good being, the sword bestows a negative level on the wielder. Once the wielder has drawn the sword in battle, she can never draw another weapon, nor get rid of the sword. It appears in her hand at the start of any combat. Only a miracle or wish frees the bearer.

Exposure to the breath weapons of two dragon great wyrms⁠—​one metallic, one chromatic⁠—​within a 24-hour span is required to destroy the Blade of Valgyr.
