Theres a farming technique for this. you fill your inventory with player's skulls or green lace which can be looted up to the max. then just place 1, 2 , 3 or 4 skull in your inventory and replace them with the items you need to farm then type @autoloot then boom! you can now loot more than one item at the same time. Sorry if my explanation is kinda confusing. I hope you get what I mean.
