I get through the Krypt every time I have enough souls to open them all. I went through the whole Krypt like 8 or 9 times and 2 or 3 times I haven't seen a single one of these. So I wonder what the pattern is if there is any. Or it's just random, maybe depending on time in the Krypt or something.

many times i got Kronika Vault in those areas in video. but also i got Vaults in starting area, when you first enter the Krypt and go outside a few steps. got it by the Dragon logo puzzle or in the Treasure Vault. or right off when you leave elevator from Courtyard to Goro's Lair. in Goro's Lair i got it several times before the One Being puzzle doors, right by Kronika's time rewinding machine and on the opposite site. i thinks its really random and could be anywhere.

yesterday i got one in Goro's dinning hall
