Enchant Type

On the available enchants, should "metal" be added? (The enchats such as Diamond, Topaz, Orthoclase) I forgot to take a screenshot, but there was a person with an Orthoclase Arbalest, and as long as I know, those "metal" enchants cannot be put on ranged weapons usually. I just thought we should add that arbalest is an exception to this rule.

Actually, the Arbalest is a metal crossbow. I would think it would allow metal due to the majority of the bow having metal on it.
