Minecraft 1.13 "Update Aquatic"

Shipwreck

It can generate upside down, right side up, or lying on its side. The ship is often missing a part - the bow or the stern, as well as the mast. But sometimes you can find fully intact ships too. The ship's hull can be made from any wood type found in the Overworld. However, each individual ship only uses two wood types.

What can you find in this structure?

There can be up to three chests inside a ship. One chest spawns in the bow, and two more in the stern. But sometimes a chest may be missing from its spot. The loot in the chests and its probability is shown below.

Underwater Ruins

Underwater ruins generate as ruined structures on the ocean floor. Although most underwater ruins generate underwater, in some cases they can also appear on land.

What can you find in this structure?

Inside all types of structures except two, you can find a treasure chest. Sometimes the chest is buried under gravel or sand. It's also worth noting that drowned spawn abundantly around the ruins.

Drowned

The drowned are a type of zombie that live in oceans and rivers. They can often be found near underwater ruins. A zombie can turn into a drowned if it stays underwater for more than 30 seconds. They are the only mobs that can spawn holding a trident. A trident drops from a drowned with a 6.25% chance. Drowned can also spawn holding a fishing rod, which has a 3.75% drop chance.

Behavior

Drowned attack in melee combat. If they have a trident, they use it as a ranged weapon. Players cannot pick up thrown tridents, just as they cannot pick up arrows fired by skeletons. During the day, drowned only swim up to attack players in the water. The rest of the time they stay on the bottom of bodies of water, ignoring players on land or in boats. Drowned holding tridents keep throwing them at players even after leaving the water. At night and during thunderstorms, they come ashore and chase players and turtles, even if those are outside the water.

Drops

When a drowned dies, it drops 0 to 2 rotten flesh. The amount increases by one for each level of the Looting enchantment, up to a maximum of 5 with Looting III. It also drops 1 copper ingot with an 11% chance, which increases by 2% for each level of Looting. This drop is only available if the drowned is killed by a player or their tamed wolf.

Trident

• A trident can only be obtained by killing a drowned; it drops with an 8.5% chance.
• A new melee and ranged weapon that deals 9 damage in melee and 8 damage when thrown.
• A thrown trident can only be picked up by the player who threw it.
• Can have unique enchantments: Riptide pulls the player along with the trident when thrown underwater and lets you "fly" during rain. Impaling deals extra damage to aquatic mobs or any creature that's in rain or in water. Loyalty returns the trident to you after it's thrown. Channeling strikes the target with lightning on a hit - it only works during a thunderstorm.

Coral Reef

A new structure that generates in warm oceans. They consist of numerous clusters of coral blocks, coral, and coral fans. These clusters come in a wide variety of shapes, sizes, and colors. You can also find a new light source here - sea pickles, which only generate in this structure.

Conduit

The conduit is crafted from 8 nautilus shells and one heart of the sea. It works on the same principle as a beacon. To activate a conduit, you need to place 16 blocks of prismarine and set the conduit itself in the center. When activated, the conduit produces the Conduit Power effect. The range of this effect depends on the number of prismarine blocks used. It can range from 32 to 96 blocks. In the screenshots above, the smallest conduit is shown on the left, and its largest version on the right, which gives the maximum range of the Conduit Power effect; additionally, all hostile mobs within 8 blocks of the conduit that are in contact with water or rain will take 4 ( × 2) damage every 2 seconds.

Conduit Power

• This is a positive effect that combines Water Breathing, Night Vision, and Haste.
• The effect lets you breathe underwater, improves underwater visibility, and increases mining and combat speed underwater.

Dolphin

Dolphins are neutral mobs that live in oceans. They spawn in groups of 3-5 in any ocean biome except frozen oceans. Dolphins usually swim in large groups, jumping out of the water to breathe. They can also move between bodies of water. When a player rides in a boat, dolphins follow along. If a player is within 9 blocks of a dolphin, they get the Dolphin's Grace effect for 5 seconds. When a dolphin ends up out of water, after a couple of minutes it starts taking damage from lack of air and eventually dies, just like a squid. On land, a dolphin actively searches for water to survive, but it can't live without air. If a dolphin stays underwater for more than four minutes, it starts drowning.

Behavior

Dolphins are attracted to items that fall into the water, which they push and chase after. If a player or another creature attacks a dolphin, the whole pod joins the fight against the attacker, attacking together like wolves. When a player feeds dolphins raw fish (cod or salmon), they swim toward the nearest shipwreck, buried treasure, or underwater ruins.

Drops

Killing a dolphin drops 0 to 1 raw cod. The amount of fish dropped increases by one for each level of the Looting enchantment. So killing a dolphin with a weapon enchanted with Looting III can yield up to 4 fish.

Dolphin's Grace

• The player gets this effect from staying near a dolphin for a while.
• Increases underwater movement speed.

Phantom

The phantom is a flying, hostile undead mob that attacks players who haven't slept for more than three in-game days. Like other undead mobs, phantoms are hurt by the Instant Health effect and healed by the Instant Damage effect, and they are also vulnerable to sunlight. The longer a player stays awake, the higher the chance of phantoms appearing. They spawn at night, in the Overworld, and the longer the player stays awake, the more of them appear.

Behavior

During the day, the phantom doesn't hide in shade or water, nor does it attack the player. Like most undead mobs, they can breathe underwater and don't drown. Having a cat nearby prevents phantoms from attacking the player. When phantoms get close to cats, they fly away, and you can hear the pet's characteristic hissing sound.

Drops

When a phantom is killed by a player or a tamed wolf, it drops 0-1 phantom membrane. The amount can be increased using the Looting enchantment. If a phantom is damaged but not killed, it can very rarely still drop loot if it later dies from sunlight.

Phantom Membrane

• Dropped when a phantom is killed.
• Used to repair elytra.

Potion of Slow Falling

• Brewed from a phantom membrane.
• Gives the player the Slow Falling effect for 1:30, though the duration can be extended to 4 minutes using redstone dust.

Turtle

The turtle is a friendly mob that lives on sandy beaches near oceans. During the day, they appear on the beach in groups of up to 5, except in the snowy and stony variants of that biome. It's important that there's sand beneath these mobs. Turtles can be placed in a boat, but they can't be put on a lead, and they'll always try to return to their home beach, where they were born or spawned. When a turtle dies, it drops up to two seagrass. When a baby turtle grows into an adult turtle, it drops one scute. There's a chance that a turtle killed by lightning will drop a bowl.

Breeding

Turtles can breed on their own without the player's involvement. But you can also feed them seagrass to start the breeding process. Baby turtles will be attacked by most hostile mobs.

1. First stage: During breeding, one of the turtles heads to a spot within 9 blocks of where it spawned or hatched. There, it lays a clutch with an animation that mimics digging, containing 1 to 4 turtle eggs. If the distance is greater (for example, if you lead the turtle far away from its usual spot), it won't lay eggs.

2. Second stage: Turtle eggs go through three stages of maturing, after which baby turtles hatch. Each stage is accompanied by an animation of green particles around the egg and a cracking sound. The maturing process can take several in-game days. That said, the process speeds up significantly between the 3rd and 4th in-game days, and in the morning. An egg will only mature if it's placed on a regular or red sand block.

Baby turtles become adults in 20 minutes, and feeding them seagrass speeds up this process. Each seagrass fed to a baby turtle speeds up its growth by 10%.

Everyday uses

Turtles can be used to build a scute farm. Scutes are used for brewing potions and crafting a turtle shell.

Scute

• Dropped when a baby turtle grows into an adult.

Turtle Shell

• Crafted from 5 scutes.
• Worn as a helmet, giving 2 armor points and the Water Breathing effect for 10 seconds while underwater.

Potion of the Turtle Master

• Made by adding a turtle shell to an awkward potion on a brewing stand.
• Grants Slowness and Resistance IV. The Resistance IV effect significantly reduces the damage the player takes from enemies.

Advancements

• - Catch a fish using a fishing rod.
• - Catch a fish using a bucket.
• - Throw a trident at a living creature.
• - Throw a trident enchanted with Channeling at a villager so that lightning strikes it.
