I've got one in my vault. It's a tier 0 so I'm guessing this retired weapon doesn't do anything.

Same here. One in my vault, none in shops anywhere, no info on subetalodge. What is this thing?

(Sorry if this counts as a necro but I didn't feel comfortable making a topic over the exact same situation lmao)

The weapon hover doesn’t show anything so if it ever was a weapon, it isn’t anymore. Looks like it’s merely a TC item now.
