Additions

Has copper, iron, gold, diamond, and netherite variants.
- Copper, iron, golden, and diamond nautilus armor now have a chance to be found in the chests for the following structures:
- Copper, iron and golden nautilus armor can be smelted into the respective nuggets.

Spawn Eggs

Added nautilus and zombie nautilus spawn eggs.

Spear

New weapon that can be crafted in wood, stone, copper, iron, gold, diamond and netherite versions.
- Each material has different stats for timing, influencing how fast they are to use.
- Copper, iron and golden spears can be smelted into the respective nuggets.
Can be enchanted with the exclusive enchantment Lunge, in addition to the available enchantments for swords.
Has a minimum reach for damage, being too close to a target will yield no damage.
- Has extended maximum reach compared to other tools and weapons.
Zombies, husks, zombified piglins and piglins can spawn holding a spear.
Has two attacks: jab and charge.
- Jab
  - Used by quick-pressing the primary action button.
  - Is a low-damage attack with knockback.
  - Has a cooldown between attacks.
  - Wooden spears have the fastest cooldown, while netherite has the slowest.
  - Can hit multiple enemies.
- Charge
  - Used by holding the secondary action button.
  - Damage is based on spear material, the player’s view angle, and the velocity of both the player and the target.
  - While holding down the button, the attack goes through three stages before returning to idle:
    - Engaged: The spear can deal damage, knockback, and dismount mounted enemies if the speed is above the required thresholds.
    - Tired: Indicated by the spear rotating to a vertical position and shaking. The spear can deal damage and knockback (but not dismount) if the speed is above the required thresholds.
    - Disengaged: Indicated by the spear being lowered, pointing downwards. The Spear gives damage but not knockback or dismount if the speed is above the required threshold.
  - The spear's range when used by mobs is half of that when used by players, but they can deal damage, dismount and knockback at lower speeds than the players.

Can be bred and tamed using a pufferfish or a bucket of pufferfish.
A tamed nautilus can be equipped with a saddle, then the player can ride it.

Once tamed, has a roaming restriction around its home position of 16 blocks with a saddle, and 32 blocks without.
Has a 5% (¹⁄₂₀) chance of dropping a nautilus shell upon death, on a player kill, unaffected by Looting.

Zombie Nautilus

A new neutral underwater mob that spawns with a drowned rider wielding a trident.
Hostile only if ridden by a hostile mob.
Behaves similar to the nautilus except that it cannot be bred.
Burns in sunlight, like other undead mobs.

- Requirements:
  - Requires the "minecraft:use_modifiers" item component on the same item.
Added the "minecraft:piercing_weapon" item component.

- Requirements:
