Just a concept but it technically works 1 list can hold up to 60,000,000 items (3x larger than large Terraria world) 4 lists can hold up to 240,000,000 items 9 lists can hold up to 540,000,000 items 16 lists can hold up to 960,000,000 items 25 lists can hold up to 1.5 billion items way bigger than terraria world but it is way too slow to fill the lists, drawing from the lists is not slow though
