The Kappa Treasure is a rare tool that you can obtain by collecting all 9 Kappa Jewels in the game. When equipped, the Kappa Treasure restores 1 fatigue point per minute.
All the Kappa Jewels/Orbs can be found in the Lake Mine, and they each appear on a very specific level. Here are the nine levels in the Lake Mine where you’ll find the Kappa Jewels (only 1 jewel per level):
- Level 0
- Level 40
- Level 60
- Level 80
- Level 120
- Level 140
- Level 160
- Level 180
- Level 255
How To Find All Kappa Jewels
Finding a Kappa Jewel is as simple as breaking rocks on the following floors of the Lake Mine: 0, 40, 60, 80, 120, 140, 160, 180, and 255.
Only one Jewel will appear on each floor, so you’ll have to go through all 9 of those levels to complete your collection.
If you don’t get a Kappa Jewel on your first try, you can try the save scum method to save time on mining.
This works by saving your game before you go down to the next level. If you don’t find the item you wanted, you can just reload the save and try again.
The save scum method takes advantage of the fact that each level in the mine resets each time you go down a ladder.
The spawn rates of the items also reload, and you can just keep going back to your previous save so you don’t run out of time or stamina before you can find a Kappa Jewel.
How To Get the Kappa Treasure
After you find the last Kappa Jewel, Kappa will appear and give you the Kappa Treasure.
He will actually show up in the Lake Mine right where you are, so you don’t have to go find him.
Note: This event will only trigger if you have an extra slot in your tool bag, so make sure you leave some slots empty before heading to the Lake Mine.
After you obtain the Kappa Treasure, you can equip it to passively restore fatigue while doing your work! 1 FAT will be restored per minute as long as the Kappa Treasure is selected in the tool menu.
