Harder Hardcore

Hardcore Minecraft isn't actually hard. You can skip the night pretty much immediately with 3 wool, making the most dangerous part of the day completely irrelevent, Elytras make it so you never have to worry about fall damage ever again, You can keep your God armor and tools forever with Mending, and I don't even need to explain how Totems of Undying literally remove the entire "Hardcore" part of the game.

This mod removes all of that beds, mending enchant, elytras, and totems of undying. Making Hardcore Minecraft actually Hardcore.
