The Snow Globe is an item that can be found in Presents with a 1/14 chance, but only in Hard Mode worlds. The Snow Globe is used to summon the Frost Legion and once used you will receive a message in the bottom left hand corner, which says; "The Frost Legion is approaching from the east/west!" in a similar manner as the Goblin Army. The Snow Globe is used the same way a Suspicious Looking Eye or Worm Food is used to summon the Eye of Cthulhu or the Eater of Worlds. It can be obtained from Presents dropped from monsters (from December 15th through to the 31st). The Frost Legion's time to arrive is much faster than the Goblin Army. The Frost Legion comes a few seconds after the first message.
