Hello everyone I am going to be showing you how to farm all sorts of creatures in Terraria. I hope you enjoy this and find it helpful. This is an overworld creature farm (non-flying creatures only.)
For overworld creatures to spawn most often put a water candle near you. Then put dirt in rows for them to spawn on. Wire dart traps at the end of the row to a 3 second timer. This will cause them to either die or fall into a lava pit (put this at the opposite ends of the row with the dart traps in it.) Fill each pit with ONLY ONE BUCKET OF LAVA so the loot will not burn. Set up a place you can stay so the mobs will be attracted to you. This is how I made my farm, it also rarely spawns mimics. Good luck!
