This is my save that I used to do my runs in the IL category. It has certain vital skills unendorsed so that they may appear first in dungeons during runs. 

Note that you must replace your save file with this backup every time you finish a run or return to fizzle, to return to default state. Otherwise, quitting to title will not save your progress for resetting purposes.

GU save file location: C:\Users\"name"\AppData\LocalLow\Aggro Crab\Going Under

The save will appear as save file #3 in-game.
