This build is designed for auto-farming XP, box and a few coins.

Just need 2 mini magnet or 1 small magnet and 2-3 pit lift, For the 3rd treasure, you can use another XP-boosting treasure as long as it doesn’t interrupt the farming loop.

The amount of XP you gain depends on the timing of EXP Party Power+. With perfect timing, you can get around 10,00-12,000 (1,000-3,000 without any boost) XP, even without a Relay Cookie.
