Lios Seafaring Dungeons Mod (1.21.11, 1.20.1) – Seafaring Adventure

Available for:FabricForgeNeoForge

Exploring Minecraft's oceans often feels underwhelming once you've raided a few shipwrecks and ocean monuments. Lios Seafaring Dungeons Mod changes that by scattering three distinct dungeon types across your world — two hidden beneath the waves and one buried underground. Created by Liopyu, this mod brings genuine dungeon-crawling excitement to biomes that rarely get attention, complete with custom loot tables and hostile mobs guarding every corridor.

Key Features

  • Three unique dungeon types — Mossy Ocean Dungeons spawn in warm oceans, Sandstone Ocean Dungeons appear in cold oceans, and Underground Land Dungeons generate beneath the surface, giving every biome something new to discover.
  • Custom loot and enemies — Each dungeon is filled with its own loot pools and hostile mobs, making exploration feel rewarding rather than repetitive.
  • Expanded exploration — New biomes and structures are introduced alongside the dungeons, encouraging players to venture further from home.
  • Biome-aware generation — Dungeon types are tied to specific ocean temperatures, so warm and cold oceans each offer a visually and mechanically distinct experience.
