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.

Defeating an Ice Queen will add 150 points (300 points) during the Frost Moon.[4]

Attacks[edit | edit source]

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 Frost Wave.png frost waves at the player.
  • She will hover over the player while raining down Frost Shard.gif frost shards below her. The frost shards from this attack deal slightly more damage (74 / 148 / 222).
  • 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 / 140 / 210).

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.

Notes[edit | edit source]

  • 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:
Debuff From Projectile Duration [db 1] Chance

1 second 2 seconds 2.5 seconds 4.17*1/24 (4.17%)
  1. In total, the chance to inflict the Chilled debuff is 100% for the Frost Wave and 66.67*2/3 (66.67%) for the Frost Shard. The Frozen debuff is inflicted with an overall chance of 16.54*127/768 (16.54%). Information taken from the Desktop version Desktop 1.4.0.5 source code, method StatusPlayer in Terraria.Projectile.cs and methods AddBuff() and AddBuff_DetermineBuffTimeToAdd() in Terraria.Player.cs There may be inaccuracies, as the current Desktop version Desktop version is 1.4.1.1.

Tips[edit | edit source]

For more elaborate strategies on defeating Ice Queen, including weapon and arena recommendations, see Guide:Frost Moon strategies.
  • 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 Warmth PotionDesktop, Console, Old-gen console, and Mobile versions, equipping a Hand WarmerDesktop, Console, Old-gen console, and Mobile versions, or equipping an Ankh Shield in the Desktop version Desktop, Console version Console, and Mobile version Mobile versions will negate these effects and potentially make the fight much less frustrating.
  • The Frozen 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.
  • 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.[5]
  • 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[edit | edit source]

  • The BestiaryBestiary entry for the Ice Queen: "If this icy towering monstrosity wishes for someone's soul, they'll surely let it go... right from their cold, dead hands."

  5. 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 1 over the result of 8 times the squared cosine of theta
