This is a Fortnite Chapter 7 Season 4 gameplay guide explaining how to unlock the hidden Temple Vault at the Stone Sanctum point of interest (POI). The vault is easy to miss, as players must first locate two invisible Temple Vault keys before they can access a secret lower level containing valuable loot.

To find the keys, players need to smash invisible pots with a pickaxe, typically located on pedestals in the north-east and south-east corners of Stone Sanctum's middle floor; only one key can be carried at a time, so each must be used before collecting the next. Both keys must then be taken to stone discs at the centre of the POI, which drains the surrounding water and reveals a lower floor stocked with rare chests and at least three epic cheat codes that grant high-rarity sprites. Players can exit via a staircase leading to a secret door back outside.
