The random deadly keybind

This mod allows you and your friends to have a little plot twist on your next minecraft world. In this mod, there will be a random 2 and a half minute timer that you will not be able to tell when it will go off, and when this happens, a random keybind will be chosen. When you click the chosen keybind, you will lose 10 hearts of damage. This keybind isn't announced and changees every 2 and a half minutes. This mod also includes a new biome with a new structure that has a magical crystal. WHen you use the magical crystal (right click), it will remove the deadly keybind and allow you to play like normal for 2 and a half minutes to 5 minutes. You can change the time and damage that this mod uses in the gamerule section.
