Ender Pearl

The Ender Pearl is an item that is dropped by Endermen upon death.

Usage
Throwing an Ender Pearl by right clicking will cause the user to teleport to its impact location, consuming the Ender Pearl, and dealing damage to the user. Wearing enchanted armor with Feather Falling or Protection reduces the amount of damage taken. If the player doesn't have enough health, the player dies after teleporting.

Ender Pearls are useful to teleport to hard-to-reach locations, such as up/down/across ravines or cliffs. (When teleporting downward, the key distance is 8 blocks -- if you're further up than that, the pearl will do less damage than jumping down would.) They are also useful to escape death, such as if the player is trapped by a group of mobs or if the player accidentally falls in a pit of lava.

Ender Pearls are necessary to craft Eyes of Ender, which are used to locate strongholds and activate End Portals. Therefore, Ender Pearls are crucial to reaching The End unless you trade with villagers for Eyes of Ender.

Ender Pearls can also be used to make special house entrances. With enough Ender Pearls, a player can place Lava where the door would be, then throw Ender Pearls through to enter, because thrown Ender Pearls do not burn up in Lava. This can prevent many types of griefing.

Bugs

 * If riding a boat, minecart, horse or pig with saddle, throwing an Ender Pearl will not teleport you but you are still damaged.
 * Throwing an Ender Pearl then going to sleep wakes you up and deals damage, but does not teleport the player.

Trivia

 * Ender Pearls can be used to teleport/move through non-solid blocks by pressing against the blocks and using the Ender Pearl at the player's feet until the player goes through.
 * Protection and Feather Falling enchantments both reduce falling damage taken from the Ender Pearl. With enough protection and enough pearls, one could travel a long distance very quickly.
 * It is possible to spawn a thrown Ender Pearl with the ID 14, but it does not teleport. This will only display the Ender Pearl sprite and disappear instantly.
 * If the player throws an Ender Pearl and then dies before impact, the player does not teleport after respawning, nor does the player take fall damage from the pearl.
 * If the player throws an Ender Pearl in survival mode and changes to creative mode before the pearl lands, the player is still teleported.
 * The player is teleported if they throw an Ender Pearl and enter the Nether before it lands. The pearl is not lost if an Ender Pearl is thrown into a Nether Portal and the player travels through the portal,the pearl will appear and land and teleport the player as if you had just thrown it.
 * Ender Pearls can travel about 30 meters when thrown straight up and about 50 meters forward when thrown in a 45° angle.
 * Ender Pearls collide with vines, tall grass, Dead Bushes, Ferns, Flowers, all kinds of Saplings, all kinds of Mushrooms, all kinds of Minecarts, Boats, and Nether Portals.
 * If multiple Ender Pearls are thrown in succession, the player can only be hurt once from fall damage within about a one second span.
 * If a player dies from Ender Pearl teleportation, it will say: hit the ground to hard>.
