Ice Queen

The Ice Queen is a post-Plantera, 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.
Defeating an Ice Queen will add 150 points () during the Frost Moon, giving the most number of points for any enemy during the event. 
== Attacks ==
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. The frost shards from this attack deal slightly more damage (74 / / ).
* She will stay stationary before spinning in the air and shooting frost shards in all different directions. The frost shards from this attack deal slightly less damage (70 / / ).
As Ice Queen's health is depleted, her acceleration and maximum horizontal speed increase. Additionally, the firing rates of her attacks increase, as detailed in the following table. Note that these changes happen as Ice Queen's health passes the listed thresholds, and are not continuous; thus, for example, her frost wave firing rate will be 2.07 waves/second at 100% health and also at 75% health, but as soon as its health drops below 75%, the rate of fire will increase to 2.22/sec.

< 10% 	2.61 	5.46 	60
== Notes ==
* During the final waves of the Frost Moon there may be several Ice Queens on the screen at once.
* The Ice Queen has a higher chance of dropping loot in later waves. See Frost Moon for more details.
* The Ice Queen's projectiles inflict the following debuffs:

== 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 Frozen debuff causes players to exit their mount. This may kill a player without immunity to fall damage 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.
* The distribution of the Ice Queen's frost shards during her twirl attack is weighted such that the projectiles have a significantly higher chance of shooting near-diagonally than near-vertically or near-horizontally. Thus, players standing roughly along one cardinal direction from the Ice Queen (up, down, left, or right from her) have a lesser chance of being hit than players standing diagonally from her.{{#tag:ref|For this attack, the frost shards are assigned an angle by being given a random, uniformly-distributed X-velocity and a random, uniformly-distributed Y-velocity, and their velocity vectors are then normalized to have a length of 15.0 (which does not change the angle). Thus, the distribution of the polar angles of their velocity vectors is nonuniform, being proportional to {{math|Ice_Queen-math-1|scale=0.7|alt={{#uesc:<esc>\frac{1}{8 \cos^2 \theta},\quad -\pi \leq \theta < \pi</esc>}}|inline=y}}.

* 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.
* The Ice Queen's name resembles ice cream, which may or may not be a intentional.
* The Ice Queen's bestiary entry may be a reference to Elsa, from the Frozen franchise, since Elsa's most famous song is "Let it Go" and the bestiary entry for the Ice Queen references the title of that song. Furthermore, Elsa is known as the Ice Queen because of her royal status, but also because Frozen is based on a book by Hans Christian Andersen written in 1844, called The Snow Queen.
