Caelum seems really hard to complete, so I guess I'll focus first on gathering enough DRUBBLE to complete Brighthollow, then I'll come back to Druantia to farm again, and lastly I'll go to Caelum.

Let me correct that, Caulum is very easy to complete, you need to buy the keys from the shop 2K each (just 5 floors).. but getting the chest to level up is really hard from my experience this far.

Btw, as I'm still in Druantia, if you need screenshots of Druantia's keys, let me know which ones do you need and I'll drop some screens.

can you send me the json that would help me out a lot... i'm think on a small site :)
you can do that by the following action

• navigate to game
• press F12 ( or right-click and inspect page)
• got network tab
• navigate to forge
• inspect response of the last call 🤣

I not possible no worries will travel back some day
