Wraith

s are hostile mobs that appear at night. They have a 30% chance to drop Undead Essence.

Omninomicon Entry
Ghostly beings composed of an ethereal substance. s employ spectral powers to defeat their opponents.

Behavior
s float around in the air aimlessly until seeing a player. Upon seeing the player, the wraith will begin floating towards the player(if the player is within 11 blocks of the wraith) or will shoot a projectile resembling a purple orb at them(if the player is more than 11 blocks away from the wraith). Like other undead mobs, s take damage in the sunlight, but, unlike other undead mobs, they do not burn in the sunlight.

Abilities
s use a melee attack that deals 2(Easy), 3(Normal) or 5(Hard) damage. They are also capable of using a "spectral bolt" attack from far away. The wraith is able to fire a purple orb that deals 7(Easy), 10(Normal), or 12(Hard) damage. s are also capable of floating up to ten blocks off of the ground.
