The Root of Corruption
The Root of Corruption is a NeoForge horror mod for 1.21.1 that adds a multi-stage boss encounter and a world that turns hostile as the fight progresses.
What it does
The encounter opens with a first small boss placed near the bedrock layer. Defeating it is recommended with a full set of Netherite armor and several Iron Golems ready. Once that boss falls, the next step is a final boss, reached by a set of coordinates. The end dimension holds a black block that players wait for, and the mod can be progressed through commands if time is short. Right-clicking to summon a second small boss, Lost Memory, is part of the chain, and it must be beaten with Iron Golems.
After the small bosses are killed, players craft Missing equipment, and recipes can be looked up with JEI or a recipe-giving event. Some drops from the small bosses are lost when they are blown up, and in that case the creative mode is the fallback. The final boss can destroy several Wardens, destroy boats and kill Iron Golems in an instant, and it can summon Evokers, Endermen and Blazes. Once the final boss is defeated, the mod's content is complete.
The Root of Corruption is open source under the MIT License and runs on client and server, so the server and every player need it. Files are published for NeoForge only, for 1.21.1, with 1.0.8 as the latest alpha file from 2026-05-01.
