Slime Crown

A Slime Crown can be made at a Demon Altar when you have 1 Gold Crown and 99 gel. The Slime Crown summons the King Slime. However, King Slime can still spawn on the edge of the world.

Tips

 * It's advised to use a Battle Potion and Water Candle instead as gold is valuable.
 * If you use the second Slime Crown when King Slime from the first Slime Crown is leaving, you will die.
