Queen Slime

Queen Slime is an early-Hardmode Hallow-themed Boss and is the Hardmode counterpart to King Slime. Her appearance is that of a massive, transparent pink slime wearing a tiara with what resembles an enlarged, more crystallized version of the Gelatin Crystal, which is the item used to summon her, inside herself.

Fighting Queen Slime is completely optional and not required for game progression, but her defeat may reward the player with useful items.

Spawning
The Queen Slime can be spawned by using a Gelatin Crystal. This can only be done in the Hallow. Otherwise, nothing will happen and the item will not be consumed.

The Gelatin Crystal can be found in the Underground Hallow alongside Crystal Shards, and they spawn in the same way as Crystal Shards. Therefore, the Gelatin Crystal needs to be mined before use. Once used, the item is consumed, and the boss is summoned.

Behavior
Queen Slime jumps around in a similar fashion to King Slime, though much faster. She periodically summons, , or. Crystal slimes will shoot several crystals upwards, heavenly slimes will fly towards the player and bouncy slimes will fire bouncing shots towards the player. After a few jumps, she does one of two things, chosen at random:


 * Will stay in one place for a few seconds, before jumping very quickly towards the player and attempt to stomp them, dealing high damage.
 * Will stay in one place for a few seconds, before firing 6 Regal_Gel.png Regal Gel that bounce twice before breaking. Sometimes, she will perform this attack multiple times in a row.

When at 50% health, Queen Slime will grow wings and begin to fly like a Slimer. Her AI also changes:


 * She will occasionally shoot Regal_Gel.png Regal Gel in 10 directions.
 * She will occasionally attempt to fly above and drop down onto the player.

Tips

 * Queen Slime herself has a relatively simple attack pattern with easy-to-dodge attacks. The biggest 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.
 * While the boss needs to be summoned in The Hallow, the fight can take place anywhere. This means you can go into a different biome once the fight starts and the fight will continue as normal.
 * In Master mode, The Black Spot mount allows you to hover over all attacks in the first phase. It also goes faster than Queen Slime in phase two. Be careful as this can despawn the boss.
 * It is highly recommended to fight Queen Slime in daylight, as at night her attacks may be hard to see.
 * Setting up a basic arena with platforms will make dodging attacks and defeating her much easier.
 * It is recommended to use Heart Lanterns and Campfires to increase Health regeneration rate by providing the Heart Lamp and Cozy Fire buffs respectively.
 * Sunflowers can also be useful, as they reduce enemy spawn rates by providing the Happy! buff.
 * Remember to use the Sharpening Station, Ammo Box, Crystal Ball, and Bewitching Table prior to the battle.
 * If you have defeated at least one of the Mechanical bosses, it is recommended to search the Underground Jungle for Life Fruit to increase your maximum health.
 * Make use of banners to reduce the threat of other monsters during the battle.
 * Using the black spot mount and a coin gun with gold or platinum coins can kill queen slime extremely fast even in master mode
 * The queen slime can be easily killed even before killing any other Hardmode bosses, and even before smashing any Demon or Crimson Altars. Doing this will be a significant head start in Hardmode as the Crystal Assasin armor it drops will be invaluable in killing the three Mechanical Bosses
 * As with most bosses she is immune to lava, however her minions are not. An arena made of lava paired with Lava Waders or Terraspark Boots can make the fight a breeze not having to worry about the minions
 * It is not advisable to have long connected stretches of platforms as you will have to deal with minions. Many disconnected platforms allow the minions to fall down away from the fight
 * Any pair of wings paired with flight boosting accessories and the Shield of Cthulhu (for the dash ability) makes dodging any and all of her attacks easy, but the minions can easily kill an ill-prepared player.
 * A Daedalus Stormbow and Holy Arrows as well as minions can kill her before too many of her crystal slimes are spawned
 * Sunflowers are almost necessary as the 25% movement speed can be the difference between life and death
