from How to Use This Document:
The purpose of Unique Magic Weapons is to give Dungeon Masters a way to add some spice to the magic weaponry found in their games without the need to create lots of overpowered special abilities. Every weapon listed in this document has a name, description, and powers (mostly rolled from the normal treasure tables). DMs never need to give players a simple “sword +1” any more. Instead, they'll be able to provide players with a unique named sword, with more character, even though the game stats for the weapon may simply be sword +1.
Unique Magic Weapon offers categorised listings of new, unique magical weapons for D&D (Basic/AD&D) and its retroclones. The items have a description and an explanation of their properties and effects.
