Biome Strongholds

Each supported biome generates a Stronghold variant with its own room layout and mechanics. The end portal is still a single End Portal Room, reached from a starting staircase, and the stronghold can be located from its eyes of ender. Rooms include large and library rooms, assorted corridors, and trial spawners with trial vaults, and loot tables are reworked. Support Ominous Trials is named as a companion mod for the trial content.

The biome variants add hazards to the layout. Desert strongholds hold a lava pitfall where stepping blocks turn to lava beneath the player's feet. Jungle strongholds include a flame emitter whose powered dispensers shoot flame particles that set entities on fire. Savanna strongholds use a steam emitter, and swamp strongholds contain a noxious gas emitter that gives nearby entities poison. Some strongholds include a spike ceiling of pointed dripstone that falls when a player steps under the blocks.

The mod runs on the server, so the server is the side that installs it, while the client can add it or leave it out. It is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, for 11 release versions across 1.21.5 – 26.3. The license is custom and the mod is not open source.
