So let me get this straight- it isn't the katastrophe, but we're getting the prize box from, the katastrophe. Like, just in case we miss the katastrophe and want to be reminded of all the fun we had running through candlestick keep for hours on end, we can now buy a prize box to do so, but we cannot actually partake in the katastrophe itself. Why on earth is this not being released with the katastrophe?
The armor is also very clearly the opposite set piece of the kat hats, except that we already have that. You might think this makes no sense, or that it's a terrible thing but honestly I think that it's sort of cool and interesting, to have multiple possible armor ends per line that actually match and are part of the same "set".
The armor is basically a chroma suit with a cat tail. :|
