How to summon Queen Slime

Gelatin Crystal. Use a Gelatin Crystal inside the Hallow. Find the crystal growing on Pearlstone or Pink Ice in the Underground Hallow and break it with a pickaxe.

Attacks and phases

First phase: bounces around fast, stomps down on you and fires bouncing Regal Gel. Spawns Crystal, Heavenly and Bouncy Slimes as she is hurt.
Teleports to you if she cannot reach you.
At half health she grows wings and flies, firing Regal Gel in all directions and trying to stomp you from above.

Strategy

Build a wide platform arena in the surface Hallow.
Dash or move sideways when she jumps high, since her stomp hits hard.
In the flying phase, keep moving horizontally and stay out from under her.
Kill her slime minions with piercing weapons so they don't pile up.
Wings or a good jump bottle make this fight much easier.
