The "Shifting Snows" update was detailed tonight for Dota 2 along with the 6.83 gameplay update. You know what that means. That's right, new goodies like maps and items plus plenty of balance changes.

First I'm going to hit you with the major additions for the update. Then I'm going to hit you with the general overview of the update. We're going to wrap it up with a look at all of the changes made to the Heroes. Ready?
WINTER MAP
Winter's grip has tightened, causing the river to ice over as deepening snow settles upon the forest paths. Yet the battle rages on! Heroes must now brave the bitter cold of day, and the freezing dark of night. Each ice-tipped tower that shatters, every shivering creep that dies on the field, becomes another step toward victory.

FANTASY DOTA SEASON 2 CHAMPIONS' TELEPORT
Raise a cheer for the victors of Season 2 of Fantasy Dota. Those who placed 1st, 2nd, or 3rd in Season 2 of their Fantasy Dota league will find a new teleport effect and trophy to show off to their friends. Well played!

NEW ON THE DOTA STORE
TREASURE OF THE FROSTED FLAME
Keep your heroes warm this winter with new armor for Luna, Sniper, Legion Commander, Drow Ranger, and Shadow Shaman. Open a Treasure of the Frosted Flame, and you'll also have a chance to find a new set for Tiny, or a rare Hexgill the Lane Shark courier inside!

TREASURE OF THE NESTED CACHE
It's a treasure that contains treasures! Open a Treasure of the Nested Cache, and you'll receive a random treasure, and have a chance to earn a special gift. You might even find a Treasure Redemption Token inside, which can be redeemed for another treasure of your choosing. It's the gift that keeps on giving.

EFFIGY BLOCK OF FROST
Create a frosty monument to your favorite heroes with a new material for Heroic Effigies! Available from the Dota Store, the Effigy Block of Frost can be used to design a frozen sculpture in your base for all to see. We're also enabling new animations for the creation of Effigies, which can be used with all materials.

GIFT WRAP
Tis the Season of Givening! Purchase Gift Wrap from the Dota Store, then use it on any bundle, courier, or wearable item to create a present for your favorite fellow warrior. You can even add a note to your recipient. After the gift has been wrapped, you can use the gift to send it to anyone on your friends list, or give it to a friend by trading it through Steam. Gift Wrap will be available on the Dota Store until January 12th, 2015.
