Citadel of Trials Data Pack transforms classic strongholds into dangerous underground fortresses packed with combat challenges and rewards. It replaces old stronghold layouts with detailed rooms like barracks, crypts, jails, and multi-level libraries. You face active mob spawners and unlock special vaults to gather equipment before entering the End. This data pack gives players a clear progression step to prepare gear, collect items like Dragon’s Breath, and test combat skills before fighting the dragon.
