King Slime is one of the three Mini Bosses of Terraria. He will spawn randomly on the surface, but his spawn chances will be increased the farther you are from the original spawn. So if your home is on the far end of the map, expect to see him every now and then. While fighting him, blue slimes will spawn from the king. There is also a ninja inside of King Slime (see picture to the right). Every time you defeat King Slime, he will drop a piece of the Ninja Outfit. Good weapons to use against King Slime include Flails, Guns, and Bows. Swords should be avoided because getting too close could cause you to take damage from him or the blue slimes that spawn from him.
