King Slime

The King Slime is a mini-boss that is, as its name would suggest, the ultimate form of slime. As the King Slime takes damage, it spawns additional slimes and also becomes smaller until defeated. It will always drop 1 piece of Ninja Clothes when defeated.

Spawning
Inspection of source code has led to the following conclusions about King Slime spawning behavior:
 * The King Slime spawns only in areas a third of the map away from the spawn point. An easy way to determine if you are far enough from the spawn point is to check for the presence of bunnies, who spawn in the inner 2/3 of the map surrounding the spawn point. If you can see bunnies, you aren't far enough from your spawn point. Only the outer 1/3 of the map is viable for the King Slime to spawn.
 * The King Slime has a 1:300 chance to spawn, meaning a Water Candle can actually speed up the process of encountering the King Slime dramatically. Standing stationary with a Water Candle has a roughly 50% chance of spawning the King Slime per day.
 * You can also use a Battle Potion to increase the spawn rate further.
 * The King Slime will only spawn during the day, above 0 depth and on a grass tile. It is possible for him to appear underground if these conditions are true and there is enough room for him to spawn.
 * There can only be one King Slime spawned at a time in any given world.

Strategy
The King Slime behaves exactly like a normal slime (it uses the Slime AI), except that it spawns other slimes after being hurt by the player. Due to its predictable nature, it is easy for a new player to defeat the mini-boss with even lower tier weapons. The only thing a new player should worry about is dodging the King Slime as it jumps about, as he deals a relatively large amount of damage per hit. To finish the mini-boss quickly, projectiles such as Shurikens or Bows and Arrows are recommended.

Digging a pit two blocks wide is an excellent tactic for fighting the King Slime, which is too large to fit in such a small pit. Placing wooden platforms on top of the pit has the added benefit of keeping the smaller slimes out.

Trivia

 * If you look closely enough, you can see that there is a ninja inside the King Slime. This would explain why you get ninja clothes when you defeat it. This is not viewable in the data-mined sprite in the table above. (Evidence)


 * The king slime may be a reference to Ninja Gaiden, in which one of the first bosses is a slime-like creature that devours you.
