The vast seas ahead
What this mod adds
- Reworks the spawn area into a lone sand/grass island surrounded by open water dotted with small flotsam camps and loot barrels.
- Builds a sealed deepslate vault beneath the island that houses the Warden of the Understone (a beefed-up wither skeleton boss).
- Drops the Barnacled Vault Key when the deep boss is slain; using the key on the island's lodestone altar awakens a prismarine heart-of-the-sea site and summons the kraken (empowered elder guardian).
- The kraken drops a Kraken Heart; using it calms the storm, expands the world border, and raises a beacon with boats to sail away.
- Boss fights are backed by persistent boss bars, special loot, and world persistence so progress survives restarts.
How to play
- Spawn on the island and gear up with the starter barrel and nearby flotsam caches.
- Dig down to the deepslate vault under spawn and defeat the Warden of the Understone to earn the Barnacled Vault Key.
- Right-click the lodestone altar on the island with the key to reveal the heart of the sea spire and face the kraken.
- Claim the Kraken Heart from the kraken and right-click it to calm the ocean, reveal the beacon, and open the way to escape by boat.
Notes and limitations
- The surrounding ocean is handcrafted within a few hundred blocks; beyond that radius the normal world will appear once the border is lifted.
- Bosses use strengthened vanilla mobs (wither skeleton and elder guardian) with custom drops rather than brand-new entity models.
- If a boss despawns for any reason, reopening with the key or revisiting the heart will respawn it as long as it has not been defeated.
