Able to increase the boxes for loot to generate? i have looting in my sword now, but the yellow text keep appearing. cuz some mod monster have large loot table and 5 is not enough.

Thanks a lot for the feedback. You can add a hopper below the farm to store the output in a chest.
Anyways, I could add a tier system for the output slots as well, if this is not working for your use-case.

What do you think should be the max. numbers of output slots for your use-case (e.g. 10 slots)?

I see there like alot of tier maybe each tier can increase 5-10? the number is random you can change.
