Contents of the Mounts of Mayhem update

Mounts of Mayhem is an ambitious update, bringing a wealth of new content to explore and conquer.

Underwater Mounts – Nautilus

 

The star of this update is Nautilus , a new sea creature appearing in the Ocean Biomes.

• Taming method: Players can tame Nautilus by feeding them Prismarine Shard or Heart of the Sea .
• Benefits: When riding the Nautilus, players gain an unlimited underwater breathing effect , making exploring Ocean Monuments and underwater ruins easier than ever.
• Enhanced Defense: To protect their mount, players can also equip specialized Nautilus Armor .

Spear Weapons and New Combat Mechanism

The introduction of the Spear represents the biggest change in combat. This is a tiered weapon with two new attack types:

• Jab Attack: A quick, short-range attack, ideal for attacking underwater mobs.
• Charged Attack: A powerful spear throw that deals significant damage from a distance.
• Lunge Enchantment: Spears can be enchanted with the new Lunge Enchantment , allowing players to perform more powerful lunges or knock back enemies.
• Jousting: With the Spear, players can organize Jousting battles with friends on their mounts, creating a new dimension for PvP.

 

New and Dangerous Mob Enemies

Minecraft biomes will become more dangerous with the appearance of new rideable mobs and enemies:

• Zombie Nautilus: Hostile mobs will ride Nautilus to attack players underwater, turning scuba diving into a real challenge.
• Camel Husks and Parched Mobs: Desert Biomes are no longer safe havens. New mobs will appear, including hostile mobs that can ride Camel Husks to chase players.
• Zombie Horse: Zombie horses have officially appeared in Survival Mode. You can encounter them at night, often ridden by other hostile mobs, creating chaotic encounters.

The Mounts of Mayhem update not only brings new content but also profoundly improves the exploration and combat experience in Minecraft. From riding a Nautilus to explore the ocean to using a spear to fight mobs and opponents, the Minecraft world is now larger and more dangerous than ever before.
