About
Biome Strongholds replaces the vanilla Stronghold with eight variants shaped by the biome where each one generates, giving each expedition a distinct layout, palette, enemies, and hazards. Across the variants, players can expect winding corridors, large rooms and libraries, Trial Spawners and Vaults with improved loot, and a single End Portal Room reached from the staircase marked by Eyes of Ender. The portal itself is assembled differently from the familiar frame arrangement: scattered End Portal Frames send particle trails toward a central Bedrock portal, which appears once all twelve frames are filled. The Desert Stronghold uses sandstone corridors, traps, and husks, silverfish, Parched, and Sandstorm Breezes; the Ocean Stronghold combines flooded and dry prismarine rooms with drowned, guardians, and Elder Guardians. Jungle Strongholds mix mossy stone rooms, hidden switches, puzzles, and enemies such as Bogged, blinding skeletons, smoking creepers, and vexes, while Snowy Strongholds feature vast icy spaces, secret doors, and frozen portal frames that require keys found throughout the structure. Swamp Strongholds are muddy, plant-covered mazes with poison-themed enemies and restorative cauldrons, while Forest Strongholds vary their wood and foliage by forest biome and pit explorers against threats including Breezes and Creaking. The copper-and-machinery Savanna Stronghold contains wall and floor traps, puzzles, and hostile mobs including Steaming Ghasts and Copper Golems; Plains Strongholds draw on Trail Ruins, hiding many portal frames in suspicious gravel that can be brushed safely or broken to spring a trap. Exploration also rewards attention to environmental clues: hidden buttons and levers reveal passages, while room challenges such as color, chest, library, and sapling puzzles can uncover treasure. Decorated pots may conceal damaging traps, and some traps embedded in structures can be collected and reused, including noxious gas, flame, steam, and blade devices.

Details
Security
No harmful code found
We checked its files and read their code, without running it.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.6 latest files: the newest file for each Minecraft version and loader. All 6 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 6 files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
