Every New Season, you get offered Seasonal Currency in Events such as Gobber's Duties, Gauntlet Events and the Monthly Calendar.
With this Currency you can get exclusive Seasonal Decorations, Costumes and Dragons.
Before a Season ends, you will be notified that you need to trade your surplus of Currency. A visible Countdown Timer appears until the Season ends.
 
Please note that your unused Seasonal Currency will now automatically be traded for Raw Amber at the end of the Season.
