Christmas

The Christmas event occurs only between December 15 and 31st. Presents are special drops available only during this time, and they have a chance to be dropped by any enemy except an enemy spawned by statues. Presents will even drop on worlds created prior to the 1.1.1 patch and lacking a snow biome. The chance to drop a present is 7.69230% (1 in 13). Among the several items that can be obtained from presents, the Snow Globe will summon the Frost Legion. Santa Claus will spawn as an NPC if valid housing is available after defeating the Frost Legion. In version 1.2.2, several items were added to the list of items obtainable from presents, as well as a new summon-able event called the Frost Moon.
