The Chest of Wintersday Past will spawn at the end of the Secret Lair of the Snowmen dungeon, when the party has taken Koris Deeprunner to the final room and his monologue has played out. Each player in the party may open the chest and will receive one Snowman Summoner (two in hard mode) and one other item from the drop list in normal mode (two in hard mode). After the chest has been opened by every player, a countdown timer will begin and players will be transported back to Umbral Grotto after three minutes.
