Frost Moon

The Frost Moon is a Christmas-themed event triggered through the use of a Naughty Present, which is made using materials available in Hardmode. It is a more difficult counterpart of the Pumpkin Moon, making it the most challenging event introduced thus far. It has 15 standard waves as well as 5 extra bonus waves.

During this event, the moon changes color to look like the face of a snowman.

Aside from the unique rewards you can get from the monsters in Frost Moon, this is also a very good source of Presents.

The Event
Like the Pumpkin Moon, there are a number of waves in the Frost Moon, and waves progress as you kill Frost Moon Enemies. Each Frost Moon enemy awards a differing number of "points" when killed. After a wave's points threshold is met the next wave begins, and the points score is reset to 0. When the player reaches Wave 15 there is a 25% chance each Ice Queen, Santa-NK1 and Everscream killed will drop their respective trophies. This increases to 33% at Wave 17 and 50% at Wave 19.

If the event is not completed by sunrise (4:30AM) the event will simply end, and all enemies will attempt to leave.
