This allows you to have 5 over powered commands, before you use this, we have an agreement to go over. I am not responsible for any destruction caused in your world, just for safe measures, please test these out in a flat world that is meaningless rather than on a world you care about. (Also note the book-thrown-on-the-ground-and-gets-despawned thing is to make sure if an admin accidentally drops it, something doesn't happen, like a non-admin/non-mod doesn't cause any destruction, if you don't like this feature, just destroy the command block that says "/kill @e[type=Item,=written_book]" but seriously, all you have to do is either take more than one book, or go back and get one)
