From Ultima Codex
Ultima Online that has grown pointless by now. Its two properties are revealing the exact properties of an item, and letting the player determine the sell value of said item. The first function now is taken over by a tooltip regardless of skill, and the second use is undermined by the fact that NPCs always pay the same price (which generally is very little). The skill should not be confused with Arms Lore, which does have a purpose.
To train the skill, players generally just have to try and guess the worth of items, there is no other way to train the skill, and no trainers exist.
