The only ones left are the North Cave person Claw and the World Tree boss. I kinda found my way through and got the mysterious cabe key. Didn't knew I just gotta check the castles and I can enter thr locked gates for the chests hehe though ot's only Sennin now that I can't find

Where is this mysterious cave? I have defeated the boss in Hades but I just can't find the mysterious cave. Is it named differently. Can anyone share a screenshot?

Where is sennin exactly? I tried all of solo huts and I still couldn't find him

Thanks! I tried going to the forest again and there it was the ladder. My next obstacle now is the Sun Labyrinth. I tried the pathway on following of the skull from your previous reply but thr treasure is not opening. It keeps saying there's a mysterious power

I can't enter the Mirror Castle because it says that it's sealed by a mysterious power. Now a red ping on Godesse's Castle but I where is its entry? It keeps telling me I need a special key on Next Castle dungeon but where do I get it? Also, I already unlocked the Oshiro Castle dungeon locks
