I don't think it's supposed to exist anymore. Idk if it's bannable to have it, but I feel like there should be some noticeable indication in a description that it's a counterfeit.
ETs and GMs can spawn in weightless iron by placing it on an armor stand which is why everyone in legit_player_vladovia has like 8 sets of iron each (in addition to the shoahcaust of the loss at brelus, still around 50% of us had chain while all of adria had full iron within 3 weeks of new map)
