Queen Slime is an early-Hardmode, Hallow-themed boss. Her appearance is that of a massive, translucent pink slime wearing a silver crown and engulfing a colorful crystal. Fighting Queen Slime is completely optional and is not required for game progression – much like her pre-Hardmode counterpart, King Slime – but her defeat may reward the player with useful items.

While Queen Slime is alive, her exclusive music Queen Slime will play. When Otherworldly music is enabled, the track Boss 2 (Otherworldly) will play instead.


Queen Slime can be spawned in the Hallow by using a Gelatin Crystal, which is consumed upon use, immediately summoning the boss. If used outside the Hallow, the boss will not be summoned and the item will not be consumed.


Just like King Slime, if she cannot reach the player, she will teleport to them.

Queen Slime jumps around in a manner similar to King Slime, though much faster and in bursts. She summons minions that attack the player as she is damaged:

After a few jumps, she remains stationary for a few seconds, then attacks in one of two ways, chosen at random:

  • Jumps quickly toward the player, attempting to stomp them, which deals high damage. While ascending, she can pass through blocks.
  • Fires 6 Regal GelRegal Gel that bounce twice before breaking. She will sometimes perform this attack multiple times in a row.

When at 50% health, Queen Slime grows wings and begins to fly above the player, similarly to a Slimer. She can also pass through blocks and her AI changes:

  • She rapidly fires Regal Gel in 10 directions.
  • She attempts to fly above and stomp the player when in close enough proximity. If she does not hit a surface after a while, she will stop and fly back to the player.
  • She can no longer teleport to the player.


  • While the boss needs to be summoned in The Hallow, the fight can take place anywhere. This means the player can go into a different biome once the fight starts and the fight will continue as normal.
  • The Royal Gel does not make players immune to the slimes she summons.
  • Despite being a Hardmode boss, developer items cannot be obtained from Queen Slime's Treasure Bag.
  • The slam attack is capable of hitting the player in the air if they are above Queen Slime when she performs this attack.
  • Queen Slime herself and the Regal Gel are slowed down by liquids. In the Queen's second phase she is no longer affected by liquids unless she is trying to stomp the player.
  • The Bouncy Slimes and Crystal Slimes will not fire projectiles while they are floating on liquids, like most other slimes.
  • In a world using the "for the worthy" seed, Queen Slime's AI is changed as follows:
    • She fires volleys of 8 Regal Gels in the first phase, and 15 in the second.
    • The orientation of the Regal Gel attack is randomized.
    • Her stomp attack is much faster.

For more elaborate strategies on defeating Queen Slime, including weapon and arena recommendations, see Guide:Queen Slime strategies.
  • Palladium armor can be useful due to the Rapid Healing buff it provides.
  • Queen Slime herself has a relatively simple attack pattern. Half the threat comes from the minions she spawns, which can fill the screen with projectiles and quickly overwhelm the player. Killing or avoiding these should be top priority.
  • Stay in the air using wings or mounts during her first phase, as many of her attacks cannot reach the player there. During her second phase, the player should stay closer to the ground while occasionally luring her back up, as they can avoid many of her projectiles and minions due to their slow and predictable movement patterns.
  • In Master Mode, The Black Spot mount allows the player to hover above all attacks in the first phase.
  • Fight Queen Slime in daylight, since her attacks may be hard to see at night.
  • Queen Slime can be killed easily before any other Hardmode bosses, and even before destroying Demon or Crimson Altars. The Crystal Assassin armor she drops will help the player survive in early Hardmode.
  • Like most bosses, she is immune to lava, but her minions are not. An arena made of lava paired with Lava Waders or Terraspark Boots can make the fight significantly easier.
  • Another effective strategy against her minions is to try to inflict multiple damaging debuffs at once. A good example of this is using the Shadowflame Knife paired with Frost Armor and a Flask of Cursed Flames, as the three debuffs are often enough to finish off any of the slimes, even if only one knife hits.
  • For magic users, the Life Drain is a very good choice for this fight. Because it deals continuous damage around your cursor, this allows you to consistently damage the boss while focusing on dodging. Since the minions spawn from the center of the boss, it will deal some damage to them right as they spawn. In addition, you gain a boost to your life regeneration while damaging an enemy.
  • Use several disconnected platforms, which can allow her minions to fall down and away from the fight.
  • Any wings paired with flight-boosting accessories and the Shield of Cthulhu (for its dash ability) makes dodging most of her attacks easy (but does not take care of her minions).
  • The Daedalus Stormbow paired with Holy Arrows and summoned minions can take care of her minions.
  • When fighting her in higher difficulties, never remain directly above multiple Crystal Slimes. Their spikes can kill the player in seconds.
  • Invisibility Potions can be used to decrease spawn rates of other enemies and prevent the Heavenly Slimes from chasing after the player. Note that taking any damage will instantly cancel the buff, however.


  • Queen Slime's AI was created entirely by developer Grox The Great, while the visual effect was created by Yoraiz0r.Verify
  • Queen Slime is one of 7 bosses with exclusive music, the others being the Empress of Light, Plantera, Duke Fishron, Moon Lord, Queen Bee, and Deerclops.
  • The feather covered in slime on her trophy resembles the sword covered in slime from King Slime's trophy.
  • Queen Slime was one of the two bosses added in the 1.4 update, along with the Empress of Light. Both are Hallow-themed.
    • The Queen is centered on the Hallow's crystal theme while the Empress has the Hallow's rainbow theme, as seen by the colors of their summon items, their attacks, and exclusive items they drop.
  • Queen Slime is one of the three bosses whose map icon does not change upon entering their second form, the others being the Brain of Cthulhu and the Santa-NK1.
  • Most of Queen Slime's drops are upgraded versions of King Slime's drops. Both the Ninja armor and Crystal Assassin armor are feudal Japanese-themed sets that do not favor a specific class. Each boss also drops a mount-summoning item (Slimy Saddle and Gelatinous Pillion), a hook (Slime Hook and Hook of Dissonance) and a novelty weapon (Slime Gun and Sparkle Slime Balloon).
    • Unlike most boss loot drops, the Hook of Dissonance's drop chance is not affected by luck, and so will always drop with a 33.33*1/3 (33.33%) chance. This might be because of the Hook of Dissonance being Queen Slime's counterpart to King Slime's Slime Hook: The latter is also unaffected by luck, because if the Slime Hook does not drop, the Slime Gun will drop.[1]
    • The Volatile Gelatin also shares a resemblance to the Royal Gel, both being the Expert Mode drops for Queen Slime and King Slime respectively and being crowns similar to that of the respective bosses covered in gel. However, this is purely an aesthetic difference and the two have completely different uses.
  • The wings of her second form resemble an oversized pair of Angel Wings.
  • The Queen Slime's crown gore that appears upon her death is different from the King Slime's crown gore. While the King's crown appears when Blood and Gore is on, the Queen's does not.
    • This is likely because not only does her crown drop on death, the wings also drop.
  • The BestiaryBestiary entry for the Queen Slime: "Hallowed slimes consolidated into a haughty, crushing force adorned in dazzling crystals. She is rumored to grow wings."
