Slime Crown

The Slime Crown is used to summon King Slime, a Boss-type enemy. While King Slime can spawn randomly at any time without the use of a summoning item (though only in the outer two-thirds of the map, laterally), the Slime Crown summons King Slime instantaneously, in any location. The Slime Crown can be crafted at a Crimson Altar or Demon Altar.
