Frost Moon

The  is an event triggered through the use of a Naughty Present, which is made using materials only available in Hardmode. It is the Christmas counterpart of the original Pumpkin Moon with increased difficulty, 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.

Enemies in and points required to reach each wave:

Total points required to reach Wave 20: 10,160
