Frost Moon



The Frost Moon is a post-Plantera, Christmas-themed event summoned with the Naughty Present any time at night, ending at dawn (4:30AM). It can be summoned any time of year and does not require the actual Christmas season. During the event, unique and highly difficult enemies spawn at high rates and attack the player. It is similar to the Pumpkin Moon event, but is more difficult and includes slightly more content. Visually, the moon turns into a snowman head, though remaining in its current phase. The event features a unique music track.

The entire event consists of 15 waves, plus 5 "bonus waves". Waves progress as the player reaches certain kill scores (though kill scores are not displayed to the player before wave 20). After a wave's required score is met, the next wave begins, and the kill score is reset to 0. Status messages will indicate when the wave has advanced, and which wave has been achieved. See the table below for the points awarded for each enemy and the score required for each wave.

The Frost Moon event always ends at 4:30AM. The goal of the event is to progress through all 20 waves before the event ends.

The Naughty Present, which summons the Frost Moon, requires materials only available in Hardmode worlds where the player has already defeated Plantera (although it can still be summoned in pre-Hardmode worlds). As such, it is intended to present a challenge even to players with the best possible equipment. In the final waves, multiple boss-level enemies are fought at once.

Frost Moon enemies drop powerful weapons, as well as pet and vanity items. Most drop with extreme rarity, and even players who manage to complete the event will find they need to do so several times before obtaining them. Drop chances for items dropped by bosses increase as waves are completed. At wave 15, there is a 25% chance each Ice Queen, Santa-NK1 and Everscream killed will drop its respective trophy. This increases to 33% at wave 17 and 50% at wave 19.

Waves

 * Total points required to reach wave 15: 3410, wave 20: 10160
 * Present Mimics may spawn at any wave, instead of wave-appropriate enemies, if there are currently less than four Present Mimics around.
 * The maximum number of bosses at once depends on the wave. While this number is reached (or possibly exceeded, for example if the player manages to somehow reach wave 9 without killing two Everscreams from wave 6), no more of this type of boss will spawn.

Tips

 * Because spawn rates for areas where Frost Moon enemies cannot spawn are also increased, a Frost Moon can be used to farm for other items, e.g., Pirate Maps at the Ocean, while completely avoiding the Frost Moon enemies.
 * The early-wave Frost Moon enemies are susceptible to the Ichor debuff, which makes a Flask of Ichor, Ichor Arrows or Bullets, or the Golden Shower very effective.
 * Players should kill the enemies as soon as they spawn to ensure that more enemies can spawn continuously in order to increase the chances of reaching later waves.
 * The Frost Moon can be a great way to obtain a large amount of coins quickly.

Trivia

 * The Frost Moon was the hardest event in the game until update, after which it was beaten by the Lunar Events.
 * This is one of the few post-1.2 features available on the 3DS version.
