Wither Boss

The Wither Boss is a Minecraft boss that can be spawned by placing a "T" shape tower with four soul sand and then placing three Wither Skeleton skulls/heads upon the top three most blocks of soul sand. The Wither Boss takes a few seconds to spawn and explodes after spawning, thus players should stay away from the boss before it spawns. When killed (which should be quite easy with mediocre gear on CombatMC) the boss drops a Nether Star that can be used to craft beacons.
