After you have found the promised land (go to my previous post to see what it is) you may go on a new quest, to find the minecraft holy grail. The minecraft holy grail can only be found in multiplayer with the following glitches: no death and unfinished shaders. You mus go to were the sun sets and there after many days of your great quest you will find a strange object, it is actually an unfinished combination of 2 elements. Now then, i recommend doing this quest with another person as it is hard, i might give you a picture when i found it.
