Did you get the one in the hive
Every single one of them :/
I roamed every single spot in the entire map using the blindfold, opened every chest, soul vault, kenshi chest til I could get just konsumables from them, reset and repeat multiple times to certify. Every 1h30 passed in the game I would hunt for the kronika chests, also depleting them. Every week I try to reopen the kenshi ones and hunt for the kronika chest just to be sure. It's been months and I still don't have that skin. Shrine gives me nothing but konsumables, althought I do think its a bug or just the rng, I don't know what to do apart from waiting for a day when will be available to be bought using time crystals in the shop.
The grind is atrocious and shouldn't be this hard/random in this kind of game, since its a fighting game and I should be using that time labbing instead. It makes Diablo III grind looks perfect in comparison, and that comes from someone who still plays Diablo III to this day.
