I'm building a network of farms underground,I'm late prehardmode, but the only hardmode items I need for my farms is bubbles and conveyors, teleporters (and temple bricks jungle grass looks not very great, temple traps are cool to, but I can acquire them now, but don't want to, farms working great without them. So as I said, I'm building completely independent network of farms, by independent I mean without any need to step from underground, and independent battle potion potion production, deathweed farm is implemented in my main farm, there's also water and alchemy station. Vertebraes I can get from my crimson farm(it's not in caverns layer so I don't need to worry about skeleton merchant and placing conveyors all over the place so he will fall in my farm). The only thing I need, and don't know if that's possible, is a sand farm. Sans is renewable thanks to antlions, very slow, but renewable. And I don't need fast farms! One sand is 3 bottles that's more than enough. Problem is, I don't know how to force antlion to spawn(I'm close to desert btw), and even if I do, how do I turn sand projectile a into sand item?
