Swords

For some unknown reason, despite the multitude of weapons available in the multiverse, this is the weapon of choice of many adventurers, exceeded in usefulness by perhaps only the 10 foot pole. Sure, some people will carry axes, but these will always be in the minority. Swords can carry a number of useful enchantments and magical swords especially seem to find their way into the hands of monsters only to be "recovered" by adventuring parties for later use. This can only be explained by the phrase "a wizard did it."
