Can items of zero resale value be created? If so, have a weapon rack and armour rack in the guild treasury that has an infinite amount of equipment at "fine" or whatever quality that is unruneable unenchantable.

get helm -> You get a helm off the armour rack.
get boots - you get a pair of boots off the armour rack.

An endless supply of "useless" equipment isn't a bad thing.

And its only useless to people of higher level. Low level people, well I guess to them its sorta priceless?
