I had an idea a while back about making the Frostbrand, Ice Bow, and Flower of Frost craftable with Glacial Bars, but... people like Ice Mimics too much. So the way I thought I could take that idea was this: Just one special addition (maybe an accessory) to the drop table of Ice Chest mimics and Shadow Chest mimics, along with the usual?
Unfortunately, that means Sz's Lihzahrd Mimics' drop table will also need to become craftable, and a new accessory added for them? Lots of changes that would have to entail, for sure. I dunno.
