The frost ram returns with the Frost Challenge. This mount is described as sturdy which can leap pretty well as expected by a ram. The mount also features a really fast movement speed, plus the ability to carry quite a lot of weight. If you happen to be a gatherer, it sounds like the this mount will be the right companion.
The next reward is the avatar ring. This ring is non-tradable so keep that in mind as you unlock it. This will be awarded permanently as a border for a single character. Additionally, you can trade it to the Vanity Merchant for one Adventurer’s token.
There are also several Frost Challenge chests which will net you other rewards like Adventurer's Tomes and Silver bags. New furniture items are available as well like snowman and snowball pile, classic ice sculptures, and the Frost Igloo. Rich Noble vanity skins are also up for grabs.
