How To Beat Queen Slime in Terraria (Ultimate Guide)

Queen Slime in Terraria is one of the earliest bosses you can fight when entering Hardmode. In this article, we will cover in detail what facing this boss is like and what you should do to prepare for the fight. So get ready for the ultimate guide to beating Queen Slime in Terraria.

The Queen Slime is somewhat similar to her pre-hardmode regal counterpart however, her second phase will allow her to fly, which shakes things up quite a lot while fighting her. You need to use the Gelatin Crystal within the Hallow to spawn her. The minions she spawns are a nuisance as well hence managing them is a must.

This detailed guide covers some of the best strategies and character builds for swiftly dealing with the Queen Slime boss in Terraria.

How to Spawn Queen Slime?

Spawning Queen Slime

The Queen Slime is a Hallow-themed boss encountered in Terraria during the early-Hardmode phase. To summon the Queen Slime, one must acquire a Gelatin Crystal and use it within the Hallow or Underground Hallow. When the Gelatin Crystal is used outside of these areas, it fails to summon the boss and remains intact.

The Gelatin Crystal is among the few naturally occurring items capable of summoning bosses. It can be discovered on Pearlstone or Pink Ice Blocks within the depths of the Underground Hallow. Regrettably, this item cannot be crafted and must be personally sought out.

Once the aforementioned blocks are shattered, it yields the summoning item required to call forth the Queen Slime. Regardless of the time of day or depth of the player’s location, as long as they stand within the boundaries of the Hallow, the summoning item can be used to initiate the encounter.

How to Defeat Queen Slime?

Defeating Queen Slime in Terraria boils down to the class you are using. Some classes will find it harder to beat this boss, while for others, it will be a breeze. We will go over which weapons best suit the class when fighting the boss.

Melee Class Strategy

Having the right arsenal is crucial when facing the Queen Slime, especially considering the swarm of slimes she summons and her ability to take flight. Here are some recommended weapons for the battle:

  • The Shadowflame Knife is a great choice due to its precision and the bouncing projectiles it unleashes.
  • During the Queen’s initial phase, the Sergeant United Shield proves extremely effective in dispatching her minions. However, it may struggle to keep up during the second phase.
  • Flails like the Drippler Crippler, Chain Guillotines, or Dao of Pow are valuable in this encounter, offering both high damage output and extended reach.
  • The Frostbrand or Beam Sword are also solid options, as their projectiles deal decent damage and possess considerable range.
  • The Amarok or Hel-Fire (or Yelets if you have already defeated a mechanical boss) are formidable weapons worth considering.

In terms of armor, the Titanium set provides commendable stat bonuses along with the powerful Titanium Barrier. Alternatively, Adamantite armor sacrifices the special set bonus in favor of higher overall stats. Melee users may opt for the Frost Breastplate and Mythril Greaves combination to further enhance their stats.

Frost armor is another viable choice, offering similar melee bonuses as Adamantite or Titanium sets. Additionally, it inflicts a useful Frostburn debuff that often proves lethal to spawned slimes with just a single scratch.

Ranged Class Strategy

For dealing with Queen Slime and her summoned slimes, a variety of ranged weapons can prove effective. Consider the following options:

  • The Dart Pistol or Dart Rifle equipped with Crystal Darts is highly useful due to its substantial damage output and the semi-homing ricochet ability. This combination can swiftly eliminate nearby slimes.
  • The Daedalus Stormbow, while primarily known for taking down smaller slimes, can also inflict significant damage to the Queen Slime. Pair it with Holy/Ichor Arrows and a Magic Quiver for optimal results.
  • Ore Repeaters are slightly weaker alternatives, but they still pack a punch and can be reliable choices in this battle.
  • The Shadowflame Bow, Marrow, and Ice Bow offer improved stats but lack arrow variance, making them viable alternatives depending on your playstyle.
  • The Onyx Blaster is an incredibly potent weapon against the Queen Slime when utilized with Crystal Bullets and complemented with Ichor. However, it may struggle against regular slimes. An alternative option is the Megashark, which is even stronger but requires defeating The Destroyer.

As for armor, Adamantite armor sacrifices the special set bonus in exchange for higher overall stats. Ranged users can switch to the Frost Breastplate and Mythril Greaves combination for even greater stat boosts.

Frost armor provides similar ranged bonuses to Adamantite or Titanium sets and inflicts a valuable Frostburn debuff that can often eliminate spawned slimes with just a single strike.

Mage Class Strategy

Mage Class Strategy


When engaging the Queen Slime as a mage, several powerful weapons can be employed. Consider the following options:

  • The Meteor Staff delivers high damage output but depletes mana rapidly. It is recommended to have an ample supply of mana potions to sustain its usage.
  • The Crystal Storm is another formidable choice, especially when combined with the Blessed Apple mount in the second phase. Queen Slime’s collisions with the projectiles can greatly increase the overall damage per second.
  • The Life Drain proves invaluable for swiftly eliminating large groups of slimes with minimal aiming required. It also provides noticeable health regeneration. However, it is not recommended to rely on it solely for healing, as its performance against individual targets is lackluster, and it drains mana heavily.
  • The Nimbus Rod can provide additional DPS against all targets. Casting it before initiating the fight is a viable strategy since it does not continually drain mana, and its clouds linger for a considerable duration.
  • The Sky Fracture is a versatile option, capable of easily hitting Queen Slime herself and effectively dealing with her slime minions. However, precise aiming in the second phase may pose some difficulty.
  • The Spirit Flame inflicts significant damage but is most effective during the second phase. In the first phase, it is challenging to control its target selection, often hitting a slime minion instead of Queen Slime (or vice versa). During the second phase, it becomes useful against Queen Slime if you can closely track her, as the minion slimes are less likely to be in close proximity.
  • The Crystal Serpent can deal substantial damage to Queen Slime due to her large size. However, it may struggle to dispatch the smaller slimes effectively.
  • The Golden Shower is a valuable asset in this fight, thanks to its ability to lower Queen Slime’s defense. Additionally, as a penetrating weapon, it can independently clear out the slime minions.
  • If you have previously battled The Twins, the Rainbow Rod crafted from the souls is one of the best options against the Queen Slime. Its area-of-effect damage, piercing capabilities, and homing projectiles allow for swift elimination of the minions while continuously damaging the Queen Slime.

For mage armor, the Forbidden set is a viable choice due to the efficiency of its set bonus. Alternatively, if you have already defeated a mechanical boss, Hallowed armor becomes an excellent option, as the Holy Protection buff greatly enhances survivability.

Summoner Class Strategy

When facing the Queen Slime, various summoning weapons can be advantageous. Consider the following options:

  • The Sanguine Staff is the top choice for this fight due to its high drop rate, damage, and aerial tracking. It consistently hits the Queen Slime during the second phase. Note that the Dreadnautilus is a rare and formidable enemy in its own right.
  • Despite being a pre-Hardmode summon weapon, Abigail’s Flower becomes viable in Hardmode, especially when paired with the Firecracker. It receives a buff that enhances its effectiveness against the Queen Slime.
  • Whips such as the Durendal, Spinal Tap, and Snapthorn may not be reliable as primary weapons, but they significantly boost the damage output of minions through their damage tags. Their effectiveness can be further amplified by using Flasks, particularly Ichor Flasks.
  • The Firecracker boasts high DPS when used as a primary weapon, especially when both the player and their minions focus on the same target. However, its short range makes it a risky choice unless combined with Obsidian armor.
  • The Cool Whip’s snowflake effect and extended range prove useful for clearing out minions in the first phase. In the second phase, if minions like the Spider Staff struggle to hit Queen Slime, whips might be your only source of damage. In this scenario, the Cool Whip deals the most damage.
    • Combining the Firecracker for the first phase and the Cool Whip for the second phase, along with Obsidian Armor, yields better results than using either one alone, particularly when relying on weaker minions like the Spider Staff and Imp Staff.
  • The Pirate Staff provides the highest damage among summoning weapons available at this stage, provided no mechanical bosses have been defeated. However, obtaining it requires significant luck, and it may be more practical to opt for easier-to-obtain alternatives. The Spider Staff serves as a slightly weaker but more accessible option. It’s worth noting that both minions struggle against Queen Slime’s second phase due to their inability to fly. One possible remedy is to use the Imp Staff during the second phase, dismissing ground summons and summoning weaker aerial Imps instead.
  • The Queen Spider Staff can be quite helpful in dealing with the numerous minion slimes, depending on the placement of its sentries.

Summoners benefit from using the Forbidden armor set due to the efficiency of its set bonus. For whip users, Obsidian armor proves useful, thanks to its substantial increases in whip speed and range. Spider armor is a solid choice for summoners due to the increased number of minion slots it provides.

Other Strategies

Other Strategies to defeating Queen Slime

Gravitation Potions:

Queen Slime’s aerial mobility and gravity-affected attacks make the Gravitation Potion an exceptionally effective strategy during the second phase. By utilizing this potion, you can easily maneuver out of her attack range while maintaining an advantageous position.

It is recommended to equip a potent weapon with ample range or summon flying minions like the Imp or Sanguine Staves. This setup allows you to effortlessly evade her attacks while flipping gravity and counterattacking while falling.

Related:

To further enhance your maneuverability, using the Slime Mount is advised, as it boosts falling speed in space and enables you to quickly escape her proximity if she gets too close. The combination of the Slime Mount and the Shield of Cthulhu can turn her second phase into a breeze, granting you significant control and maneuvering capability.

Skybridge:

Utilizing a long sky bridge for the battle can greatly simplify the task of evading the spawned slimes. In her initial stage, Queen Slime moves relatively slowly, but once she transforms into her winged form, she can keep pace with the mounts summoned by the Goat Skull and Blessed Apple.

However, it’s important to exercise caution when changing directions, as all previously summoned slimes will be waiting for you.

As an alternative strategy, during the second stage, Queen Slime follows a relatively predictable pattern. By running back and forth on the sky bridge and skillfully jumping over projectiles, you can maintain a consistent height while Queen Slime hovers around the same level.

This predictable movement makes targeting her much easier and increases your chances of landing successful hits.

Minecart Track:

Employing a lengthy Minecart track can significantly simplify the defeat of this boss, as it allows you to match her swiftest speed and surpass the majority of her minions. This strategy bears resemblance to utilizing a mount on a skybridge, providing you with an advantageous position and mobility during the battle.

Water Walking on the Ocean:

By utilizing Water Walking Boots or Water Walking Potions, an effective strategy for fighting Queen Slime involves engaging her over the Ocean. This approach takes advantage of the unique properties of the ocean environment.

Queen Slime’s projectiles will sink into the water, rendering them harmless, and a significant portion of the slimes she summons are unable to shoot while floating.

It is crucial to maintain constant movement when employing this strategy. In the first phase, Queen Slime will periodically submerge into the ocean and teleport to your location. Therefore, staying mobile is essential to avoid her attacks and maintain a favorable position throughout the battle.

Lava Layer:

Similar to most bosses, Queen Slime herself is immune to lava, but her minions are not. Exploiting this weakness, you can employ a thin layer of lava to eliminate the majority of her minions.

Related:

To further enhance this strategy, consider equipping Lava Waders, Terraspark Boots, Water Walking Potions, or Obsidian Skin Potions. These items will provide you with the necessary protection and mobility to effectively decimate Queen Slime and her minions while maneuvering through the lava.

What are the Difficulty Differences?

Difficulty Differences Queen Slime

The boss has different stats depending on the difficulty and the phase it is in. These differences are as follows:

Classic Mode

In Classic Mode the Queen Slime in Terraria has the following stats:

  • First Phase and Second Phase:
    • Damage: 60-80
    • HP: 18000
    • Defense: 26
    • Knockback Resistance: 100%
    • Immune to Poisoned, Shimmering, and Confused

When the player is out of reach, Queen Slime will submerge into the ground and teleport to a nearby location, or directly on top of the player if there are no solid blocks available for teleportation. She displays a burst of faster leaping movements, periodically pausing to attack in one of two randomized ways.

In one attack pattern, Queen Slime charges energy within her crystal and launches six Regal Gel projectiles. These gravity-affected projectiles bounce off solid blocks twice before dissipating.

During another attack pattern, Queen Slime leaps toward the player, phasing through blocks in an attempt to position herself directly above them. She then performs a ground pound, creating a damaging shockwave on nearby solid blocks upon impact.

Once Queen Slime’s health drops below 50% of her maximum, she sprouts large wings and takes flight, effortlessly passing through solid blocks. In this phase, she no longer attempts to teleport but continues using the attacks from her first phase, albeit modified for midair combat.

Related:

In her airborne state, Queen Slime charges energy in her crystal and unleashes Regal Gel projectiles in ten directions, initially forming a circular pattern before spreading outward.

She also tries to position herself above the player while in flight, descending rapidly to create a damaging shockwave upon impact if they are in close proximity. However, if there are no solid blocks to land on, she cancels the attack and returns to the player.

Furthermore, when Queen Slime sustains damage, she summons one of three smaller slime minions to aid her:

  1. Crystal Slimes, which fire crystal spike projectiles at the player with a frequency of approximately one spike every 0.83 seconds.
  2. Bouncy Slimes, launches pink bouncy gel projectiles at the player at a rate of approximately one projectile every 0.67 seconds.
  3. Heavenly Slimes, which fly towards the player, attempting to inflict contact damage.

Expert Mode

In Expert Mode the Queen Slime in Terraria has the following stats:

  • First Phase and Second Phase:
    • Damage: 120-160
    • HP: 28800
    • Defense: 26
    • Knockback Resistance: 100%
    • Immune to Poisoned, Shimmering, and Confused

The only changes in Expert Mode are:

  • The Crystal Slimes she spawns will fire three crystal spikes instead of just one every 0.42 seconds instead of 0.83.
  • The Bouncey Slimes will fire their projectiles every 0.5 seconds instead of 0.67 seconds.

Other than the ones mentioned before, all the rest of the behavior stays relatively the same as Classic Mode with the added challenge of more HP and damage output.

Master Mode

In Master Mode the Queen Slime in Terraria has the following stats:

  • First Phase and Second Phase:
    • Damage: 180-240
    • HP: 36720
    • Defense: 26
    • Knockback Resistance: 100%
    • Immune to Poisoned, Shimmering, and Confused

Queen Slime in Terraria has a similar behavior as in Expert Mode however her overall health and damage output is massively increased.

Is Queen Slime Harder Solo or With Friends?

When fighting solo, you have the advantage of being able to solely concentrate on your own character and actions. This can make it easier to manage your positioning, dodging, and attacks without distractions.

Bosses in Terraria generally have increased health and damage when faced with multiple players. Therefore, fighting Queen Slime solo means you’ll be dealing with her base stats, which may make the battle comparatively more manageable. Queen Slime’s minions will primarily target you, allowing you to predict and counter their movements more effectively.

Having more players means the potential for increased damage output. Coordinated attacks from multiple players can rapidly deplete Queen Slime’s health, making the fight shorter and potentially easier.

Related:

With friends joining the battle, Queen Slime’s minions will have more targets to choose from, potentially reducing the pressure on each individual player.

Cooperation and communication among friends can lead to better coordination, such as assigning specific roles (tank, healer, damage dealer) or sharing beneficial buffs and items. This teamwork can enhance survivability and optimize damage during the fight.
