Endermen drop when killed. They teleport the player where ever it lands when the pearl is thrown, at the price of some health. Combined with Blaze powder they make the Eye of Ender, which is useful for finding strongholds. They are thrown like Snowballs and teleport you to wherever it lands. Regardless where it lands though, you pay a price for teleportation: You lose health.
- Before update TU7 they were useless.
