Celestial blade

Celestial blades were the favored weapons of planetars.

Description
Celestial blades were powerful enchanted bastard swords sized for planetars, (who could stand almost as tall as ,) and they weighed about. The planetar's weapon always glowed with light equivalent to that of a torch. It was usually enscribed with holy symbol of the deity whom the planetar served. While not at all likely to be sold in any shop on the Material Plane, scholars estimated their value to be around 18,000 gold pieces. They radiated an evocation aura of moderate strength to those who could detect magic.

Powers
A celestial blade had no special powers beyond its light and its general magical enhancement, but in the hands of a planetar or other celestial, it could cut through the inherent supernatural defenses of most evil creatures.
