Winter's Spite is the Christmas/winter add-on for Fade Beyond the Veil. 

This 11 Page Add-on featuring winter themed content and includes a new way to play Fade Beyond the Veil. The new game mode is a hex crawl across a frozen waste while engaging in skirmish battles. You will encounter 5 new enemies and must prepare well as towns are rare and there will be many battles on the way to the Pillar of Spite. If you manage to reach the Pillar you will battle Varantur and his Heart of Winter. 

The Winter Rewards table gives you random new items including equipment with the new Frostbite, Bitter and Ice Proof Tags or some new Trinkets. You also have a chance at getting the Frostborne Sword, the weapon of Varantur that deals increased damage if your foe has dealt any harm to you.
