Never use a bow because then it will just teleport before it hits so it's a waste of a bow and arrow.you can't really push an enderman of a cliff and lava not so much either but if you make it teleport or try to push it in water. Never look in an enderman eye then you will just die right away or he will get really mad at you and try to kill you with his fist. Enderman's can teleport anywhere at anytime.
