Lios Seafaring Dungeons
by Liopyu
Lios Seafaring Dungeons adds underwater and underground dungeon structures to worlds, with custom loot, enemies and boss rooms for players to explore and clear.
What it does
Underwater dungeons are generated beneath the ocean floor, and mossy variants appear where the climate is warmer. Sandstone variants are placed in colder ocean regions, while Underground Land Dungeons are large structures found beneath the surface of the world rather than in open water.
The mod places new dungeons into both underwater and underground areas of a Minecraft world. Each dungeon type gives a different route through the terrain, and the structures hold their own loot tables, hostile mobs and, in some cases, boss rooms.
Installation needs no client mod: the environment is server-side only, so players join without installing it. Files are published for Fabric, Forge and NeoForge, with the latest build 0.0.7 for 26.3, and the mod is released under All rights reserved, so it is not open source.
Key features
Oceanic dungeons
Underwater dungeons in several climate variants, from mossy warm-ocean ruins to sandstone cold-ocean structures.
Underground land dungeons
Large dungeons placed beneath the surface, adding exploration away from the ocean.
Custom loot and enemies
Each dungeon carries its own loot tables and hostile mobs, so the rewards and threats differ from vanilla structures.
Boss rooms
Some dungeons end in boss rooms that players must conquer before the structure is cleared.
