Sunken Spires Data Pack fills your ocean biomes with the lost ruins of an advanced prismarine civilization. It adds many new places to explore underwater, from fallen cities to strange floating spikes. You can fight new mini-bosses to get special loot or brush away sand at new archaeology sites. This data pack gives the oceans a fresh and mysterious look while keeping the vanilla game feel.

Sunken Spires Data Pack

Features:

  • 11 Unique Structures: The pack generates new buildings and ruins all across the ocean floor.
  • New Mini-Bosses: Some locations have tough enemies that drop special helmets when you defeat them.
  • Archaeology Sites: You can find hidden treasures by brushing suspicious blocks in certain ruins.
  • It works perfectly on multiplayer servers because it only uses vanilla blocks.

  • Conduit Ruins: Spawns a working conduit surrounded by rings of prismarine.
  • Large Fossil: Generates a massive dark prismarine rib cage with an active conduit inside.
  • Ocean Temple: Gives you a layout similar to the desert temple with four loot chests.
  • Prismarine Forge: Traps an Elder Guardian near two chests and a piece of ancient debris.
  • Prismarine Trial Chamber: Spawns an 11-room dungeon with 15 trial spawners, vaults, and a boss that drops a buffed helmet.
  • Sunken City: Generates a full underwater town with five houses and a central square.
  • Trident Shrine: Hides a free trident inside a ring of sharp spikes.
