A guildmate (Spylenz) has just obtained a Quicksilver Helm ([1], [2]) from a red treasure box. This is the first time I have heard about the helm/any drop like this (An equipment that has no recipe, and isn't found anywhere else, that is), although I do remember seeing devs wearing a quicksilver set before.
So, I'm wondering: Have any of you seen or obtained "rare" drops like this from treasure boxes? Perhaps even from some certain monsters?
i got a jelly shield (2-star) from an item box once, think it was in tier 1. i was pretty happy about that, even though i didnt really need it. dont know how often stuff like that drops, but doesnt sound as rare as what youre talking about.
