Deep beneath the waves of your Minecraft world lies a massive, teal-colored fortress made entirely of rare prismarine blocks. Before you can grab those highly prized wet sponges or blocks of gold hidden inside, you have to survive laser-shooting Guardians and the dreaded Mining Fatigue curse. This guide gives you the exact strategies needed to conquer the deep ocean biome and claim your rewards.
Taking on this underwater structure requires much more than just holding your breath. You need water breathing potions, powerful helmet enchantments like Respiration, and a clear plan to navigate the confusing maze of rooms. Knowing exactly where the three Elder Guardians spawn and how to block their laser attacks turns a deadly swimming trip into a massive payoff for your survival base.
Key Takeaways
- Successfully navigating an Ocean Monument requires essential preparation, including Water Breathing potions, Depth Strider III boots, and milk buckets to counter curses.
- You must locate and defeat three Elder Guardians hidden in the top and side wings of the temple to permanently lift the debilitating Mining Fatigue curse.
- After clearing the bosses, break open the central dark prismarine cube to claim eight gold blocks and explore the hallways to harvest highly valuable sponge rooms.
- Draining the flooded monument using a grid of sand and dry sponges provides a massive, ready-made shell for a custom underwater base or an efficient prismarine farm.
Essential Gear For Underwater Survival
Before you enter the deep ocean to conquer an Ocean Monument, you need to prepare your inventory with the right survival gear. Your first priority is brewing several Potions of Water Breathing and Potions of Night Vision so you can see and survive in the murky depths. Without these potions, navigating the dark temple halls while dodging Guardian lasers is nearly impossible. You should also equip a diamond or iron helmet enchanted with Respiration III to give you extra breathing time just in case your potions run out. Finally, make sure your boots have the Depth Strider III enchantment. This specific enchantment allows you to swim at normal walking speeds, which is crucial for dodging attacks and exploring the massive structure quickly.
Once you get close to the monument, an Elder Guardian will hit you with the Mining Fatigue III effect, making it incredibly difficult to break blocks. To counter this frustrating curse, pack plenty of milk buckets in your inventory. Drinking a bucket of milk instantly clears the fatigue effect, giving you a brief window to break through walls or mine the gold blocks hidden inside the central chamber. You also want to bring a stack of standard wooden doors to create emergency air pockets. When you place a wooden door on the ocean floor or inside the temple, it creates a small space of breathable air where you can safely refill your oxygen meter. These simple wooden barriers will save your life if you accidentally run out of potions during an intense underwater battle.
Defeating The Three Elder Guardians
As soon as you swim near an ocean monument, a ghostly fish face will flash on your screen and give you Mining Fatigue. This annoying effect makes breaking blocks almost impossible, so you need to eliminate the three giant Elder Guardians hiding inside. These massive bosses control the temple and protect the valuable sponge blocks and gold. To get rid of the curse, you must navigate the confusing underwater maze and take down all three of these laser-shooting enemies. Once they are gone, you can finally drain the water and mine freely.
Your first target is the easiest to find because it waits in the very top room of the structure. Swim up to the highest point of the monument and look for the square penthouse area. Since you cannot break through the roof yet, swim down to the front entrance and make your way up the central staircase. Bring a few potions of water breathing and a trident with the Loyalty enchantment to deal heavy damage quickly. Trap the boss in a corner of the room and strike it repeatedly until it drops a wet sponge.
After clearing the top room, you still need to hunt down the remaining two bosses located in the left and right wings of the temple. Swim back down into the main maze and move horizontally toward the outer edges of the building. The interior is filled with dead ends and regular Guardians, so place dirt blocks or use kelp to mark the paths you have already explored. You will eventually find a large open chamber on each side of the monument where an Elder Guardian is waiting. Defeat both of these enemies to completely lift the mining curse and claim the temple as your own.
Finding The Gold And Sponge Rooms
Now that you have defeated the three Elder Guardians and your screen is free from that annoying mining fatigue effect, you can finally claim your prize. Your first major stop inside the monument is the central treasure chamber. Look for a large cube made entirely of dark prismarine blocks sitting right in the middle of the temple. Grab your pickaxe and break through this dark outer shell to reveal your reward. Inside this hollow cube, you will find exactly eight shiny gold blocks waiting to be added to your inventory.
After securing your gold blocks, your next goal is to hunt down the highly valuable sponge rooms. Unlike the central core, these rooms spawn completely at random, so you might need to explore every single hallway to find them. Look for tall chambers where dozens of wet sponges hang down from the ceiling like strange underwater vines. A single monument can have multiple sponge rooms, or it might occasionally generate with none at all. Simply mine these wet sponges with any tool, and you can later dry them in a furnace to help drain water for your future ocean building projects.
Draining The Monument With Sand And Sponges
Once you defeat the three Elder Guardians and cure your mining fatigue, you can start the massive project of draining the water. Your first step is to create a grid system using blocks that fall with gravity, like sand or gravel. Stand on the ocean surface and drop these blocks all the way down to the ocean floor to build tall walls around the monument. Grouping the structure into smaller sections, typically around five by five blocks wide, makes the draining process much easier to manage. This grid prevents the surrounding ocean water from flowing back into the areas you are trying to clear.
With your sand grid securely in place, you can put those newly looted sponges to work. Place a dry sponge right in the center of one of your sectioned grids to instantly absorb a large sphere of water. You need to work your way through the monument room by room, placing blocks to seal off doorways before dropping your sponges. If you leave open connections to flooded hallways, the water will simply rush right back in and ruin your progress. Keep a furnace nearby, or build a quick portal to the Nether, so you can easily dry out your wet sponges and reuse them for the next room.
Clearing out all that water takes a lot of patience, but the final result is worth your time. A completely dry monument gives you a massive, ready-made shell for a unique underwater base. You can also tear down the interior walls to build a highly efficient prismarine farm. This farm will spawn regular Guardians constantly, giving you an endless supply of prismarine shards, sea lanterns, and raw cod. Just remember to light up your new empty space with torches so regular hostile mobs do not spawn inside your hard-earned structure.
Celebrate Beating the Ocean Monument
Taking down an Ocean Monument is a massive achievement. Surviving the constant laser attacks from Guardians and overcoming the dreaded Mining Fatigue effect takes serious skill and preparation. You have successfully cleared out the dangerous Elder Guardians and secured the hidden gold blocks tucked away inside the dark rooms. Now that the water is drained and the temple is safe, you can relax and enjoy the rewards of your hard work. The toughest underwater battles are behind you, leaving you with a massive space ready for your personal touch.
Your inventory is probably overflowing with amazing loot that will change how you build in your survival world. Those wet sponges you collected can be dried in a furnace and used to easily clear water out of rivers or flooded caves. You also have a fantastic supply of glowing sea lanterns, which make a beautiful and clean lighting choice for modern houses or garden pathways. The unique prismarine blocks you mined are perfect for crafting a custom aquarium or an intricate castle roof. Start brainstorming your next big project, because you now have the rare materials needed to make your base look spectacular.
