Guide:King Slime strategies

The King Slime is usually an easy boss, this page gives some strategies for the boss.

Armor
Lead/Iron or Higher

Weapons
Lead or iron bow or better.

The Pit Strategy

 * The Equipment: You will need 2 platforms of some sort and a ranged weapon(preferably a Gold Bow or a Platinum Bow with plenty of Unholy Arrows or other piercing arrows like the Jester's Arrows).

First you will need to make a pit around 4 by 2(2 left to right and 4 up and down). Then cover the top with platforms. Lastly summon the boss using the Slime Crown, wait for him to come or retry and then fire away!

The Wings Strategy
This idea takes advantage of his big size, but small jump height. This strategy is optimized for Hardmode players, but can be used in Easy mode.

Add-Ons
While using the Pit method, there are several modifications you can make to them to make them more efficient. One such thing is to make it slope to the sides from the top at an angle with a thin layer of lava to kill it easily without losing the loot. Another variation is to make a bunker completely out of dirt and have a thin layer of lava on top. This will kill King Slime without any input from the player! You could also have a Super Dart Trap connected to a timer/pressure plate to kill it. The possibilities are endless!

For the Bunker method, you can add pits on the side at least 4 blocks deep to keep as many blue slimes as possible from hurting you. You can also raise the walls or make a small roof so that he can't jump all over the place. Again, the possibilities are ENDLESS
