“The lord of all things slimy.”
King Slime is an optional Pre-Hardmode boss. Due to its low stats and predictable attacks, it is considered the easiest boss in the game by most players.

Spawn Condition
King Slime can be spawned by fulfilling any of these conditions:
- Rarely in the outer lateral sixths of the map, during daytime, and only on grass, replacing a normal Slime's spawning.
- At the end of a Slime Rain.
- Using Slime Crown.
As with almost all bosses, it despawns if every player involved are dead.
The Fight
King Slime is very similar to a normal Slime: it moves by hopping to the player and attempts to make contact, which deals damage. The pattern of his jumps is predictable and repeatedly: two normal, one small, and one high. After the high jump, the King Slime can make teleport to the player. This, with his huge size and predictable movement, makes the King Slime easy to hit.
Getting too far away from King Slime will make it teleport to the player, meaning that the player cannot escape by simply running offscreen. However, this can be taken advantage of, as it can get stuck in enclosed spaces.
King Slime becomes smaller and faster the lower his health is, which makes him harder to hit. He will also summon Blue Slimes as he gets damaged to harass the player. These can draw the player's attention towards the Blue Slimes and waste ammo and time on them instead of King Slime, so the use of piercing weapons or ammo is important.
Old-gen console and
The main difference between these versions with Desktop, Console, and Mobile is that it does not teleport; it can be eternally stuck in small to medium-sized enclosures if it spawns there. Aside from this, it's mostly the same.
Expert mode
There are not many changes to the King Slime itself besides its higher Damage and Health. However, when damaged it will spawn Spiked Slimes(Desktop, Console and Mobile versions) in addition to regular Blue Slimes. Those can throw volleys of spikes at a short distance, so having a weapon that can pierce multiple targets and attack from a range will be necessary to avoid being bombarded to death.
General Strategies
Terrain Preparation
King Slime is one of the few bosses in the game that lack the ability to go through blocks. This can be exploited as follows:
- Make one or two platforms above the ground; King Slime will eventually teleport to ground level and the player can easily hit him from the platforms. If he moves to the upper platforms, falling down for a brief time before jumping back up will cause him to fall down as well.
It is possible to exploit the King Slime's large size in Old-gen console and versions by making him stuck in-between blocks.
Campfires are easy to obtain and provide a regeneration boost. Heart Lanterns can also be used, but are much harder to craft. Sunflower and Bast Statue(Desktop, Console and Mobile versions) increase movement speed and defense respectively, and should be used if obtained. A Star in a Bottle greatly increases mana regeneration, which is useful for mages without Mana Regeneration Potions.
Since King Slime spawns Blue Slimes, a Blue Slime Banner(Desktop, Console and Mobile versions) is a good idea to provide offensive and defensive buffs.
Gearing Up
Armor
Armor is not very important in this fight; however, some suggestions are below.
- Cactus Armor is a cheap option, as it is easy to obtain and provides a useful thorns effect (Desktop, Console and Mobile versions) dealing damage to any slimes that run into the player. In Expert or Master Mode, better armor is recommended due to King Slime's buffed HP and attack power.
- Pumpkin Armor is also cheap and more powerful than Cactus armor due to its set bonus.
- For all classes, Silver Armor or Tungsten Armor can increase survivability significantly in Expert or Master Mode. Platinum Armor is even better but is made from a rarer ore. If the player is looking for defense but does not have platinum in their world, Jungle Armor provides more defense than Gold Armor.
If the player has difficulty using lower-tier armors, one of these more advanced armors can be obtained:
- Gladiator Armor(Desktop, Console and Mobile versions) is extremely powerful for melee users due to its set bonus, but are rare drops from Hoplites(Desktop, Console and Mobile versions). Ancient Shadow Armor is similarly powerful, but are also very rare drops from Eater of Souls and thus are Corruption only.
- Fossil Armor(Desktop, Console and Mobile versions) with a Gi(Desktop, Console, Old-gen console and Mobile versions) optimizes for Ranged damage, and is fairly easy to obtain.
- Wizard set or Jungle armor is best for Mages.
- Flinx Fur Coat(Desktop, Console and Mobile versions) are the best choice for summoners paired with any high-defense helmet and leggings, ideally Jungle armor.
Weapons
Most weapons can be used to fight this boss without difficulties, except for weak, close-ranged melee weapons like the Umbrella. Piercing weapons may be preferred, to hit both the Blue Slimes and the King Slime himself.
- Melee
- Swords such as the Blade of Grass and Starfury are the best options available
- The Enchanted Sword is great as well, but more luck dependent.
- The Ice Blade is also viable.
- The Thorn Chakram is a good option to keep the boss at range, but can struggle against the hordes of slimes. The Trimarang(Desktop, Console and Mobile versions) is more rare, but performs similarly to the Thorn Chakram.
- The Storm Spear(Desktop, Console and Mobile versions) can penetrate the hordes of slimes and damage the boss from range with its projectile
- The Rotted Fork has higher damage than the Storm Spear, but lacks the projectile
- The Amazon(Desktop, Console and Mobile versions) is the best yoyo available.
- Ranged
- A cheap and powerful option is a Bow, such as the Gold, Platinum, or even Tendon, Demon Bow
- Frostburn Arrows or Jester's Arrows are the preferred ammo type, due to the high single target damage of the former and the piercing effect of the latter.
- The Blood Rain Bow(Desktop, Console and Mobile versions) is the strongest bow available, however it can be tiresome to obtain.
- The Snowball Cannon is another strong ranged weapon.
- If the player has done some fishing, Frost Daggerfish(Desktop, Console and Mobile versions) are strong and can pierce.
- If the player has explored the underground desert, Bone Javelins(Desktop, Console and Mobile versions) are very effective on the boss itself. Similarly, Bone Throwing Knives(Desktop, Console and Mobile versions) are good for clearing the slime minions.
- All guns are very effective against King Slime, although they are harder to obtain than the other ranged weapons.
- The Musket or The Undertaker are the easiest to obtain out of all guns, only requiring a single Shadow Orb/Crimson Heart.
- The prefered ammo type is Musket Balls, as Silver Bullets and Tungsten Bullets are too expensive and/or tedious to amass.
- Magic
- Gem staves are the most common magic weapons in this part of the game. The Emerald staff and all stronger staves do well against King Slime. The Wand of Frosting(Desktop, Console and Mobile versions) is another easily obtained magic weapon that does well in this fight.
- The Crimson Rod can be helpful in this fight, although it requires having broken Crimson Hearts.
- Though extremely rare, the Gray Zapinator(Desktop, Console and Mobile versions) is incredibly powerful, provided the player has already defeated one of these bosses: Eye of Cthulhu, Eater of Worlds, Brain of Cthulhu, Queen Bee, Skeletron
- The Demon Scythe is an incredibly powerful weapon if access to The Underworld is available.
- Summoning
- The Snapthorn(Desktop, Console and Mobile versions) is the best whip available, it will deal damage significantly. However, getting it requires Underground Jungle materials.
- The Leather Whip(Desktop, Console and Mobile versions) is a weaker alternative, yet an easier to obtain option.
- The best summon weapons at this part of the game are the Flinx Staff(Desktop, Console and Mobile versions) and the Vampire Frog Staff(Desktop, Console and Mobile versions).
- The Abigail's Flower(Desktop, Console and Mobile versions), is a weak choice, yet efficient if there are no other summon weapons available.
Accessories
Like weapons, most accessories can help, but accessories obtained in chests are usually enough to defeat King Slime. It is unlikely that players will have access to the Tinkerer's Workshop at this stage of the game, so combined accessories are not listed below.
- Hermes Boots, Dunerider Boots(Desktop, Console and Mobile versions), Flurry Boots or the Sailfish Boots(Desktop, Console and Mobile versions) can assist with horizontal mobility.
- If obtained, Fledgling Wings(Desktop, Console and Mobile versions) are amazing for extra mobility in the air.
- (Old-gen console and 3DS versions) The Flying Carpet is also a very good accessory since its ability to hover can make the King Slime unable to reach the player.
- Any double jump accessories such as the Cloud in a Bottle greatly increases vertical mobility.
- A Band of Regeneration boosts health regeneration, increasing survivability.
- While usually not useful in combat, the White String(Desktop, Console and Mobile versions) is cheap enough to craft that it can be crafted over and over again to get a Warding or Menacing Modifier. Similarly, Zombies can be farmed for a Shackle with good modifiers.
Potions
- Ironskin Potions and Regeneration Potions greatly increase survivability.
- Any food that grants the Well Fed or better should be used.
- Swiftness Potions increase mobility.
- Ale or Sake(Desktop, Console, Old-gen console and Mobile versions) provide useful melee buffs
- Archery Potions increase the effectiveness of bows.
- Mana Regeneration Potions are very important for mages, as it allows for very quick mana regeneration.
- Magic Power Potions make magic weapons more potent.
- Summoning Potions give summoners an extra minion.
Specific Strategies
Platform/Minecart strategy
Create one or two rows of platform about 18-20 blocks off the ground and at least 35-50 blocks long. Walk back and forth along the platform, firing at King Slime. If he or his slimes reach the platform, drop down temporarily and use hooks or double-jumps to return; this will cause King Slime and his minions to drop down as well, following you.
While it takes more work, making a minecart track instead of platforms can give you an even greater speed advantage, and can be useful for further fights in the game. If you can't make a very long track, put bumpers on the end. King Slime will have a hard time trying to teleport to the player because of the speed attained on a Minecart.
Lava Pit Strategy
Because King Slime can be harmed by Lava, a good strategy is to use a Lava Bucket to make a long strip of land with a small amount of lava (shallow enough so items don't burn) and then make some widely placed platforms. The player can jump, use Rocket Boots, or employ a Grappling Hook to move between platforms. Just be careful to not jump in the lava if you don't plan to use Obsidian Skin Potions. This strategy works with his teleports, and the minions will all die from falling in the lava. The player doesn't have to focus on fighting, because the lava will dish out major damage. The player can also skip the platforms and use a Obsidian Skin Potion, and just evade by running under King Slime, or use Rocket Boots to fly over.
Death Box Strategy
In Old-gen console and , upon the player's death, the King Slime will attempt to travel off-screen in order to despawn. However, the King Slime cannot travel through solid blocks, so he can easily be trapped in a small area until death.
- A solid box must be constructed. The box should be large enough to hold the King Slime, yet not so large that he can still wander off-screen.
- A bed should be placed within the box. In order to make the bed usable, it may be easiest to build a small cubicle within the box to hold the bed.
Before the King Slime spawns, the player should be inside the box with his spawn set on the bed. Once the King Slime awakens, he will teleport within the box to attack the player. The player should deal any damage he can to the King Slime at this time. The King Slime should inevitably kill the player and attempt to hop off screen. However, he will find himself trapped in the box and will not be able to leave. The player will respawn at the bed and is free to deal any additional damage to the King Slime before his next death. Repeat this process until the King Slime is defeated.
Weapons and traps that can deal damage to the King Slime during a player's death will greatly speed up the battle, such as the Crimson Rod, Dart Traps, or a thin layer of lava.
Since this strategy revolves around the player's death, hardcore players should avoid implementing this strategy.
