Smooth Stone

Unlocking the Potential of the Deep Ocean Building an advanced mob farm in Minecraft is more than just a matter of placing blocks; it is an exercise in managing the game's internal spawning algorithms. In the ProdigySMP, the need for gunpowder is absolute. Whether for TNT to excavate massive 64x64 pits or for rocket propulsion via Elytra, a standard "bow-tie" farm simply doesn't provide the yield necessary for endgame engineering. The goal is to hit a production rate of roughly 1,900 to 2,500 gunpowder per hour. To achieve this, we look toward the deep ocean biome. Selecting a deep ocean biome is a strategic necessity. Mob spawning occurs within a 128-block radius of the player. By building far out over the water, you effectively eliminate the need to light up thousands of dark caves beneath the earth. The ocean surface and the deep water beneath provide a "blank slate," ensuring that every single mob the game attempts to spawn is forced into your specific collection chambers. This guide will walk through the construction of the "Giant Stone Donut," a high-efficiency creeper farm that utilizes mechanical AI manipulation rather than passive wandering. Essential Materials for the Master Builder Before heading out to the coordinates, you must ensure your Shulker Boxes are stocked. This farm is resource-intensive, particularly in its demand for wood and stone. Using Smooth Stone is highly recommended for its clean visual grid, which makes counting block distances significantly easier during the complex circle-building phase. **The Inventory Checklist:** * **Building Blocks:** Approximately 35 stacks of Smooth Stone. This provides the structural integrity and the spawnable surface area. * **Optical Logic:** 14 stacks of Trapdoors. These are the most expensive component. You need them to manipulate the creeper's pathfinding, as they perceive an open trapdoor as a solid block they can walk on. * **Spawn Prevention:** 2 stacks of Carpets. These are placed in a specific grid to prevent Spiders from spawning, ensuring the farm remains purely for gunpowder. * **The Aggro Team:** 16 Snow Blocks and 8 Carved Pumpkins to create 8 Snow Golems. These act as the "bait" that draws the creepers into the killing floor. * **Collection Logistics:** 9 Hoppers, 6 Chests, and 9 Campfires. * **Vertical Access:** 2 stacks of Ladders and 2 Water Buckets for creating an infinite source. Phase 1: The Collection and Killing Floor The foundation of any successful farm is its collection system. If the items aren't harvested and stored correctly, the entire endeavor is a waste of durability. 1. **Platform Construction:** Start by building a 4x3 platform at sea level. Place your three double chests at one end. 2. **The Hopper Array:** Connect all nine hoppers into the back of these chests. Ensure they are all feeding toward the storage; a single misaligned hopper can cause a backup that despawns your loot. 3. **The Kill Chamber:** Place your nine campfires directly on top of the hoppers. This is a "fire and forget" killing method. Unlike Magma Blocks, campfires don't require the player to be nearby to deal damage, and they destroy the mob without destroying the loot. 4. **Water Logic:** Build a wall two blocks high around this 3x3 hopper area. Place water in the corners to create a flow that pushes any stray drops toward the center collection point. Above the kill chamber, place fence gates and open them. Creepers will fall through these, unable to pathfind back out. Phase 2: Geometry and the Spawning Circle This is where the build becomes technically demanding. The "Donut" shape is designed to maximize the 128-block spawn sphere while keeping the mobs close enough to the center to be aggravated by your Snow Golems. 1. **Measuring the Radius:** From the center of your kill chamber, extend out 11 blocks in all four cardinal directions (North, South, East, West). 2. **Building the Circle:** To create the perfect spawning circle, follow this specific pattern from your 11th block: Place 5 blocks, then step down and place 3, then step down and place 2, then five single blocks diagonally, then 2, then 3, then 5. Repeat this for all four quadrants. This creates a massive circular platform. 3. **Filling the Void:** Once the outline is complete, fill in the entire interior with Smooth Stone. This is your primary spawning real estate. 4. **Spider-Proofing:** Spiders require a 3x3 area to spawn. By placing Carpets in a grid with a two-block gap between each, you break up the 3x3 requirement. This ensures that only Creepers and Skeletons can spawn. Phase 3: AI Manipulation with Snow Golems Creepers are generally passive until they see a player or a cat, but for this advanced design, we use Snow Golems to create a high-volume "aggro" system. 1. **The Center Hub:** In the exact center of the donut, build a small 5x5 square with a 3x3 hole leading down to the kill chamber. 2. **Golems in Glass:** Place your Snow Golems in small containment cells behind fence gates around the center hole. 3. **The Baiting Mechanic:** When a creeper spawns on the platform, it will see the Snow Golem. The Snow Golem will attempt to throw snowballs at the creeper. The creeper, in its attempt to reach the golem, will walk over the open Trapdoors you've placed over the center hole. Because mob AI treats open trapdoors as solid ground, they will walk directly into the pit. 4. **Height Control:** Place trapdoors on the ceiling of the spawning platform. Minecraft calculates height in a way that Creepers (who are slightly shorter than two blocks) can spawn under a trapdoor, but Skeletons and Zombies (who are exactly two blocks tall) cannot. This makes the farm 100% Creeper-exclusive. Troubleshooting and Optimization Even the most professional builders encounter snags. If your farm isn't producing the expected 1,900+ items per hour, check these common variables: * **The AFK Height:** You must stand exactly 115 to 128 blocks above the collection chests. If you are too low, mobs will spawn in caves underground or on the ocean surface. If you are too high, the mobs in the farm will despawn before they hit the campfires. Use Ladders to reach the "sweet spot" at Y-level 188. * **Light Levels:** Ensure the roof of your donut is completely solid and that no light is leaking onto the spawning platform. Mob farms require a light level of 0 to function at peak capacity. * **Tick Lag:** In a multiplayer SMP environment, server ticks can occasionally skip. If you find yourself falling through your own farm or Elytra crashing, it is often due to the server struggling to process the massive amount of mob AI movements. Conclusion: The Spoils of Engineering Once the last Smooth Stone is placed and you've reached your AFK platform, the rewards are instantaneous. Within minutes, the chests will begin to fill with the sulfurous bounty of the Creeper. This farm isn't just a building; it's an engine that powers the rest of your world. With thousands of gunpowder units, you can now produce enough TNT to level mountains or enough rockets to explore the farthest reaches of the End. You have transitioned from a survivalist to a master of the world's mechanics.
