Ice Queen

The Ice Queen is a Hardmode mini-boss that spawns during the Frost Moon event. She is the equivalent to the Pumpking from the Pumpkin Moon, being the Frost Moon's most powerful enemy, coming in at the last waves of the event, and being the event's only flying boss.

Her behavior is characterized by astonishingly fast movement and evasive maneuvers while making constant ranged attacks against the player. She randomly cycles through the following attacks:
 * She will sweep across the screen from left to right while shooting at the player.
 * She will hover over the player while raining down below her.
 * She will stay stationary before spinning in the air and shooting Frost Shards in all different directions.

Tips

 * Both of the Ice Queen's attacks will inflict the Chilled debuff, which slows the player's movement speed, and Frost Waves will sometimes inflict the Frozen debuff which completely immobilizes the player. Drinking a, equipping a , or equipping an Ankh Shield in the versions will negate these effects and potentially make the fight much less frustrating.
 * The Chilled debuff causes players to exit their mount and may kill a player if inflicted at a high point in the sky
 * The Ice Queen is most vulnerable while executing her "Ice Twirl" attack, when she begins to spin in place rapidly, shooting Frost Shards in all directions. This is the only time she stays in one spot.
 * To mitigate her damage, using wings and possibly movement enhancing accessories for chasing and dodging, in addition to equipping a Cross Necklace/Star Veil combined with healing (Spectre armor/Vampire Knives), proves very effective.

Trivia

 * On versions, Ice Queen is considered the third strongest enemy in the game, the strongest being the Dungeon Guardian and the second strongest being Duke Fishron.
