This datapack simply replaces (almost) every hostile mob in the game. It leaves any mob that is necessary to get to the End and beat the game. This datapack was designed for use in a YouTube video, and you can play it for a real challenge. While similar to [https://modrinth.com/datapack/wardens-challenge](Wardens Only) by MCLegoMan and https://youtube.com/@JudgeAlex, this datapack varies slightly in how the wardens are spawned in and handled.
