WHERE & HOW TO FARM
Where to farm
The Underworld floor menu, advancing through the available sequence to floor 108; check the menu for Depths access after the final clear.
The Underworld is a post-campaign sequence of 108 floors, and completing it opens the Depths as a separate endgame activity. This is a progression route rather than a repeated loot farm: each floor has an exploration area, the Netherscape, followed by a Crucible containing its boss. You must defeat that boss to advance. Before entering the Crucible, explore as much of the Netherscape as your build can safely manage and collect Jizo Kodama when practical; entering the Crucible closes the route back. Prioritize reliable clears over exhaustive exploration if survival is becoming difficult. Select the next available floor after each clear and continue through the sequence. When the final floor is complete, check the Underworld menu for the Depths entry. The Depths has its own challenges and rewards, so this guide ends at the unlock rather than prescribing a build or a Depths farming route.
