18w15a[1] is the thirty-first snapshot released for Java Edition 1.13, which adds most of the features from Bedrock Edition beta 1.2.14.2: dolphins, blue ice, conduits, and icebergs.

Additions[edit]

Blocks[edit]

Blue Ice
Conduit
  • Crafted using 1 Heart of the Sea and 8 Nautilus Shells.
  • Can be activated by placing prismarine, prismarine bricks and/or sea lanterns in 5x5 open squares around it.
    • When active, will affect nearby players in water with the Conduit Power status effect.
  • A complete structure will fully power the conduit.
    • Emits a strong glow, at light level 15.

Items[edit]

Heart of the Sea
  • Used to craft conduits.
  • Not available currently in survival.
Nautilus Shell
  • Used to craft conduits.
  • Can be obtained by fishing.
  • Drowned can spawn holding a nautilus shell.

Mobs[edit]

Dolphins
  • Spawn in all oceans except frozen.
  • Are neutral. Like wolves and zombie pigmen, dolphins will attack in groups if one is angered.
  • Can be fed using raw cod, but they do not breed.
  • Sometimes drop cod on death.
  • Play with nearby items by picking them up and dropping them after a short moment.
  • Occasionally jump out of water.
  • Can also jump between disconnected bodies of water.
  • Chase after boats and jump over water surfaces.
  • Suffocate after spending too much time on land.

World generation[edit]

Icebergs
  • Generate in frozen oceans.

Gameplay[edit]

Conduit Power
  • Given when a conduit is activated.
  • Stops the breath meter from running out, gives underwater night vision and increases mining speed.
  • When active at full power, the range will increase and hostile mobs within 8 blocks will take damage.

General[edit]

Options
  • Added "Biome Blend" distance video option.

Changes[edit]

Fluids[edit]

Water
  • Has a new texture.
  • Now only blocks 1 light per block, instead of 3.
    • This only affects newly placed water.
  • Underwater vision from previous snapshots is gone; water is darker at lower depths.
  • Ocean variants have their own water colors, and the swamp water color has been changed.
  • In newly generated chunks, it is less likely to find frozen oceans next to warm oceans, etc.

Mobs[edit]

Spawning
  • Mobs can now spawn on top of ice.

Gameplay[edit]

Swimming
  • It is now possible to swim through one block holes again.
  • The transition between swimming and normal state is now smoother.
  • Sprinting at the surface of water no longer makes the player swim; instead they stay at the same altitude constantly.

General[edit]

Optimizations
  • Optimized fog rendering.
Splashes
  • Added "Thanks for the fish!".
