Automatic killing prevents certain drops and experience, but is safer as the player is not required to be near the mobs. What a mob farm produces depends on location and the type of grinder used to kill the mobs. One could try to funnel the mobs through Nether Portals to circumvent the restrictions. This reduces the amount of functioning farm designs considerably. The Nether is difficult to farm, as water evaporates and most mobs are immune to fire. Superflat worlds provide higher spawn rates than other worlds, as the missing air pockets underground reduce the amount of dark places. You can also locate your base below it to ensure that you are always close enough to spawn monsters. To produce loot, you must stay at the height of the farm.įarms constructed under an ocean can provide the best during day and night, as the ocean limits the viable spawn locations to open areas underground except for drowned, which spawn underwater. However, building one in survival is rather dangerous, and due to their height they stop working completely when you descend underground to mine resources. Due to the rules Minecraft applies to spawning mobs, this makes the choice of a location for the mob farm a difficult problem.įarms placed on the surface can provide good drop rates during the day, when it is one of the few spots of dark ground, but has a sharp drop in effectiveness during nighttime, when the entire surface is dark enough to support mob spawning.įarms built underground have a time-independent drop rate, and remain within your personal spawn range for hostiles when you go mining, but their effectiveness depends on the amount of unlit caverns in your vicinity, which provide alternative places for mobs to spawn.įarms floating high in the sky can achieve the best spawn rates during the day and night and you are far away from caves, as they represent the only viable spawn ground. The purpose for the farm is to provide a large area that is a viable spawn position for the intended targets, and to kill the mobs quickly. 3.3.3 Large chamber fully automatic design.
