Relayer
From UO Excelsior Wiki - Ultima Online Free Shard
A re-layer deed (more simply known as a relayer) lets you turn an item from one slot to another. For example, turning your favorite leveled weapon into a shield or shoe. It will take up the new equipment slot yet retain all of the statistics of your weapon. Another example of this would be to turn a helm into a shirt. A third example of this is turning a two handed weapon (2 slotted) into a one handed weapon (1 slotted).
With careful planning you can utilize re-layer deeds to fully customize your character's clothing without losing the effort you've put into your leveled weapons while increasing your over-all power.
