Minecraft wiki entry for Defeating_an_End_city, associated text: The bow will be your secondary weapon, for taking out shulkers. It is ineffective against the endermen, since they will teleport away from the arrow, but it works against the shulkers. You should enchant your bow with Power IV or V, to deal as much damage as possible, and Infinity, so that you don't run out of arrows while exploring. Unbreaking is also recommended, but not required. Flame is extremely useful, because shulkers will almost never teleport if they get set on fire. Punch is ineffective, since they are immune to knockback. Shulkers will deflect arrows if their shell is closed, so wait for them to open their shell before shooting them.
