The merchant grinned “Dear sir, I noticed you had your eye on that charm. Might I interest you in a little bit of its history? Of course I would. I will have you know, that charm has seen its way through many an adventure, and saved the lives of many of the adventurers therein. Legend tells that it was crafted centuries ago by Yurid Norcral, the greated Dwarven runesmith to ever live. Later it was said to have been enchanted by ancient Elven magics which have since been lost to the ages. Quite a rare find.”
Weapons or equipment that is heavily relied on can be "named". Then the equipment begins to gain abilities beyond those of normal equipment. They might siphon off some of the experiances of their owners (1 to 5%) and level up on thier own. Could be an unintenitional way of creating artifacts. Ships could become sturdier or seem to just barely outrun the worse of a storm that would have surely sunk another vessle, swords could fumble less or resist dulling more, a farmers plow could turn stones aside easier. Anything that is depended on as much as an inividual can depend on as much as another individual could be "named".
