Since last season (season18) started, there's been the 3 menagerie swords apparently craftable in the API.
Look at my name.
I have 350k+ kills with lightweight swords alone, counted as masterwork kill counts. Can you imagine my frustration in these missing legendary items? The API just updated after being down all weekend, and yet they're still there. 0% guardians found any of them. Is it some secret in castellum we're yet to discover? Somone who understands how to read the game files please look into this!
