WHERE & HOW TO FARM
DIY Boss Rush custom boss route
DIY Boss Rush door after completing Trial 3 at least once.
Before you go
- Unlock Boss Rush and clear Trial 3 once.
- Have the bosses or versions you want to select unlocked.
- Choose a cell spending goal for the end of the custom run.
Farming steps
- Enter the DIY door and open the boss selection menu.
- Choose from the bosses and versions available in your save.
- Build a sequence focused on the encounter you want to practice or the cells you want to collect.
- Start the custom trial and fight each selected boss in order.
- Pick up cells dropped during the fights and maintain a build that can handle the selected sequence.
- Complete the route and reach the end-of-run spending point.
- Use the cells at the Legendary Forge or Collector before leaving.
- For practice, include the target encounter and only the supporting fights you need to make the session manageable.
- Check that a selected version is unlocked before planning the route around it.
Repeat, collect and use
Repeatable after the DIY door unlocks. Cells are mode-local and spent each run; the route has no end chest reward.
Common mistakes
- Searching for DIY before clearing Trial 3; finish that trial once to open the door.
- Assuming every boss version is selectable; choose only from the options the menu makes available.
- Leaving cells unspent because there is no end chest; use the Forge or Collector at the spending point.
When to stop or switch
Stop after the target boss practice or desired cell spending is complete; revise the sequence if it is longer than the goal requires.
