A place where we can go and buy every armor, weapon, and enchant scroll to test. Make an area combat aswell. After leaving the test area, everything that was purchased inside gets deleted or store in test area specific storage. This way if someone makes a +12fid for shits and giggle, they can still mess around with it in the combat area.
I envision a row of npc shops with each category of items for 5k ea and enchant scrolls for 500a each.
