Seasonal Events are month long events featured throughout the year, which include a Season Pass, Gobber's Duties, a Seasonal Market with season-specific items, and Seasonal Collections. While Seasonal Events start on different dates every year, they always last for 30 days. To check the remaining time, you can open the Season Hub as there will be a timer at the top of screen.
Every Seasonal Event features a Season Pass. The Season Pass contains various rewards such as resources and items themed around the season (Decorations, Card Packs, and more). To advance through the Season Pass, Season Pass Points must be collected.
How do you get Season Pass Points to progress? That's where Gobber's Duties come in. Gobber's Duties are featured throughout the season in multiple formats (daily, weekly, and once per event). They require you to complete tasks of varying difficulty which will grant you Season Pass Points and some extra rewards.
Seasonal Events also feature a Season Market. In this market, you can trade in the Season Currency you have collected throughout the event (for example, Colorful Eggs) for special rewards such as Card Packs, dragons, Costumes, and more! Season Currency can be obtained from the Season Pass, Gobber's Duties, Monthly Calendars, and 7-Day Calendars.
Any season-specific goodies you collect throughout the season will be automatically checked in your Seasonal Collection. Be sure to check your collection periodically via the Season Hub to claim the rewards when you collect something new!
Once a Seasonal Event is over, any remaining Season Currency will be converted to Raw Amber and Season Pass Points will be reset.
