"He's snow cold and sad!"
The companion version of Frosty the Snowman is in the first second of the The Nate Before Christmas event, Recruit Frosty the Snowman. He occupies the center of the third column of the formation and has the debuff "Blue Christmas", which reduces the Base DPS of adjacent Crusaders by 20% and occasionally freezes a random adjacent crusader reducing their DPS to 0. However, their buffs and abilities are still active while frozen.
