Skeleton

Skeletons are ranged hostile mobs who can shoot arrows.

Spawning
Skeletons spawn on any solid surface with a light level under 7. They can also have the chance to spawn in dungeons via Monster Spawners.

Behavior
Skeletons spawn in dimly lit areas, and will burn in sunlight. When skeletons are nearby, their presence is indicated by the intermittent soft rattling sound of their bones. Skeletons will chase any player they see within 16 blocks, and will climb stairs, navigate mazes, and traverse other complex obstacles in order to get within shooting range. When they are within 8 blocks of the player with a clear line of sight, they will stop chasing and start shooting the player with arrows. If the player moves more than 16 blocks away from the skeleton, it will cease pursuit.

The skeleton's accuracy is poor. When their target is closer, skeletons shoot faster, but do less damage. To account for gravity, skeletons aim 0.2 blocks higher for every block horizontal they are from the target.

If a skeleton's arrow hits certain hostile mobs, that mob will then attack the skeleton the same way it would attack the player, given it was not hit by the player first. If a skeleton is attacked by another mob (usually another skeleton), it may attack that mob, reorienting on the player once that mob is dead.

Skeletons normally attack with a bow and when wielding, they will move at about the player's walking speed.

Skeletons are also able to climb ladders, but only when forced to, as their AI does not handle ladders in a special way.

Like zombies, skeleton burning occurs at dawn when the sun is 15 degrees or greater above the ground. They will attempt to find shade or water to keep from burning. Unlike zombies, which will always chase the player if they see one, skeletons usually will not exit the shade area even if attacking a player.
