cave of memories questions

[primal goblet]

Okay, so I’m an idiot and steamrolled through the cut scene. Was there an explanation to actually get in? I’m doing the daily gachas and doing the maps but just making sure I didn’t miss anything because it’s locked still. 😅

If cave access is still blocked then you haven’t completed its unlock yet - unlock for CoM is the advanced altar being fully completed (3rd altar)
