How To Raid Minecraft Ocean Monuments

Ocean Monuments

Mobs you will encounter:

The Guardian: Ocean Monuments are inhabited by dangerous fish-like creatures called the Guardians. These underwater mobs will attack you with a kind of electrical beam. They also have spikes, which can damage any player who is attacking them. These Guardians are very aggressive and will attack any players (or squid!) who come near them.

The Elder Guardian: Each Ocean Monument is also guarded by three Elder Guardians. This, more powerful version of the Guardian is bigger. stronger and nastier than the ordinary kind. In addition to the spines and beam attack, it casts a spell called “Mining Fatigue” that makes it harder for you to break blocks. This means you will have to defeat the Elder Guardians before you can get to the treasure.

Fighting the Guardians: Killing the Guardians will be a difficult job. You will need sufficient weaponry and armory, preferably bows and arrows, sword and iron Armour or better. When a Guardian is targeting you with its beam attack, you will see the beam and a stream of bubbles pointing towards you. It will take a few seconds to charge before damaging you: try to get out of its line of sight by ducking around a corner or behind a block, and you can avoid taking damage.

Preparations:

Before you go in search of Ocean Monuments you will need to be properly prepared.

Armour

You will need good armour, ideally a full set of Diamond armour. Certain enchantments will make your adventure much easier:

• Helmet enchantments:
• Respiration will be incredibly useful, as it will increase the amount of time you can last without breathing.
• Boot enchantments:
• Depth Strider will allow you to move more easily underwater. This will help you get close enough to the Guardians to attack them.

Weapons

Guardians are hard to fight, as the water will slow you down when you try to attack with a sword, and arrows don’t work very well under water. Bring your best sword and bow, and hope for the best!

Potions

• Potion of Night Vision:
• This potion allows you to see under water, and will make it a lot easier to find an Ocean Monument in the first place!
• Potion of Swiftness:
• This might help you to get closer to the Guardians and dodge away from their beam attacks.
• Potion of Invisibility:
• This can help you avoid the Guardians’ attacks.

Other EquipmentTorches

If you run out of air you can escape from drowning by placing a torch on the wall right next to you. It will fall off immediately, but just for a moment there will be an air pocket that will let you restore your oxygen level.

• Signs or Ladders:
• When you place one of these against a wall, you will get a block of air, useful to create a breathing space or to put in doorways when you have cleared the water from a room.
• Fence posts or glass panes:
• These can also be used to create an air pocket to let you breathe.
• Glowstone
• This light source will work under water.
• Enchanted Tools
• Silk Touch enchantment will allow you to collect Sea Lanterns. If you don’t have that, a Fortune enchantment will at least let you get more Prismarine Crystals when you break one.

The Rewards:

With all those Guardians, an Ocean Monument looks like a dangerous place! So why would you go there?

• Gold: 
• The Treasure Chamber of each Ocean Monument contains 8 gold blocks, hidden behind Dark Prismarine. 
• Prismarine:
• Prismarine itself is only found in Ocean Monuments, so if you want to use it in your own buildings, you have to take it from here. 
• Sea Lanterns:
• Sea Laterns are useful light sources for underwater structures. You can collect them using a tool enchanted with Silk Touch, otherwise they will break and you will only get Prismarine Crystals. 
• Prismarine Shards and Prismarine Crystals :
• These are sometimes dropped by the Guardians when you killed them. These items are used in crafting Sea Latern, Prismarine Bricks and Dark Prismarine. 
• Sponges:
• Sponges can be found in Ocean Monuments, either in rooms where they are attached to the ceiling, or dropped by the Elder Guardians.
