King Slime

The King Slime is the new Mini-Boss in version 1.0.4 The King Slime is a randomly appearing mini boss that can be found in caves and on the surface. It has 2000 HP when spawned. When you damage it blue slimes will break off of the king slime and the King Slime itself progressively shrinks in size. It drops a random piece of the Ninja set upon death. The chance of a King Slime appearing in the place of any other slime is 1:300, and holding a Water Candle will improve the spawn chance of King Slime. The King slime is not lava immune, unlike the other main bosses, making the use of lava moats is very effective. Dynamite also works very well against king slime, see if you can trap him. King slime will take away 40 of your health without armor.

A good way to quickly get a King Slime to spawn is to make a brand new map, get to one of the end sides (You must be about 1/3 away from your respawn point) and stop in the last place with grass dirt blocks before the sand. Hold a Water Candle and good luck! Remember that doing this doesn't give you 100% chance of a King Slime spawn, but a minor percentage (Like 0.47%). If you wait long enough you may have more than 1 King Slime at a Time as demonstrated here.

Tactics


A good strategy for beginners is to make a box in the ground 10x14(picture below,) and box yourself in (you may need Shiny Red Balloon, Grappling Hook/Ivy Whip, or a Cloud in a Bottle.) now use the speed glitch and wait for the boss music, or hold a water candle, or both. When the king slime comes cut yourself a way out 3 blocks tall on one of the sides, and then cut away the top, all the while dodging the king slime, wait for him to fall in, and then close off the top. go down to where you exit the box, and start attacking him. the king slime WILL NOT be able to damage you, and the only problem will be the blue slimes. If you have a few buckets filled with lava, then you can create the farm shown below, complete with a junk incinerator.

Trivia & Glitches
In Ninja Gaiden, one of the first bosses is a giant slimy monster that devours you. If you look closely in the center of the King Slime you'll see there is a ninja trapped in there. Armor that resembles Ryu's is the one that King Slime drops, so it might be a reference to that boss. While the King Slime jumps it seems like the ninja moves along with the slime.

King Slime was also the name of a boss in the Korean MMORPG Maplestory, which Terraria shares other elements with.

There seems to be a glitch on some Multiplayer Servers where the screen will say "King Slime Has Awoken" and he will be nowhere to be found.

It is possible to glitch spawn the King slime by speeding up time using the Speed Glitch. The Speed Glitch will allow you to speed up time while the Terraria window is minimized. Terraria will still be running while minimized and by listening to the music, you can determine when a King Slime has spawned. This is a very fast method to get the ninja set. An example is shown in the video Here.
