King Slime is an optional boss. He was introduced as part of a crossover with Terraria.
Summoning[]
King Slime can be summoned by placing a Crown Summoning Idol on any slime boss rune.
Behavior[]
At full health, King Slime will only begin attacking players within a 6 tile radius. Once damaged, this expands to 20 tiles.
Like other slime bosses King Slime attacks by quickly leaping towards the closest player, dealing damage where he lands and leaving behind a patch of Ground Slime.
Additionally, King Slime instantly breaks any non-indestructible objects in his path, including walls. Any pits/liquids will be filled in with Dirt, Grass, Beach or Lava Rock Block ground, depending on the rune used.
If the player moves out of King Slime's range during combat, or King Slime travels more than 25 tiles from the rune, he will return to the rune to regenerate health (10% of his maximum every 5 seconds).
King Slime will summon one Royal Slime for every 700 health he loses. The Royal Slimes will follow and attack nearby players, automatically despawning 60 seconds after being summoned.
Once King Slime reaches 30% health he will become enraged and begin moving much faster.

Notes[]
- King Slime will not spawn a Royal Slime if there are already 12 or more within a 15 tile radius of him.
- In multiplayer, King Slime gains additional health depending on the amount of players in the world. It will automatically adjust whenever a player joins or leaves the world. The Royal Slimes are unaffected.
