A King Slime is the combination of four slimes or two behemoth slimes. He is a very powerful spellcaster, but not a very good physical attacker. One can be found at the top of the mountain on Infant Isle after taking the Scout's Pledge. It is a hard boss at the time, and is suggested to be fought later in the game.
