Away to make farming less tedious:
Have a 23 stage farm run. ( ie take 1 stage from each of the S1 lvls ) and let it continue through them. And the loot keeps stacking for each lvl u complete. So at the end u will have 23 stages worth of regular loot. If you can get that far.
Have a separate button next to the regular S1 stages
Make it say 20flags to do this. If you want to farm a specific stage then fine. But if you just need general loot like backpacks and leather straps etc then good way to get “bulk” without having to replay each time.
Can start it. Put it on auto, then carry on with whatever.
