The random deadly keybind

In this mod, every 2 and a half minutes, a random keybind is chosen. This keybind is never revealed but once pressed will deal 10 hearts of damage. There is also a structure in a new ugly biome, (I am planning to make it better) there is a structure with a loating crystal. Once broken will drop a special crystal item that when used will disable the current deadly keybind feom 2.5-5 minutes (aka 1-2 times the time between keybinds). There are gamerules that change the damage and time between keybinds that you can tweak. Enjoy!
