Santa Claus

Santa Claus is a Hardmode NPC vendor that arrives after the Frost Legion has been defeated, but only during the Christmas season (December 15th-31st), after which he dies. In the, the Frost Legion does not need to be defeated and you don't have to be Hardmode and he will come randomly during the holiday season.

Santa Claus can be spawned at other times by changing your computer's date setting December 15th-31st. Changing the time back to normal will cause him to die at the next sunrise.
