35.4 Patch Notes

Patch 35.4 launches tomorrow, bringing the debut of Class Sets in Restoration of Azeroth. This update also includes a new Arena season, new events, and some bug fixes.

Restoring Azeroth, One Class at a Time

Deathwing devastated Azeroth, and now four classes are stepping up to heal what was broken. Introducing: Class Sets! Druid, Hunter, Paladin, and Mage each receive a Restoration of Azeroth Class Set, a focused release of new cards built entirely around a single class. Class Sets roll out in three waves over the course of the year, with four classes per wave, one after each major expansion. (Check out our in-depth Class Sets blog for more details!)

Each Restoration of Azeroth Class Set includes seven unique cards: 1 Legendary, 2 Epics, 2 Rares, and 2 Commons.

Arena Updates

Dual Class Arena Returns for a New Season

This season brings back Dual Class Arena! You'll choose two classes, then draft cards from both to create new combinations and strategies. With Patch 35.4, all ongoing Arena runs will end, and the new Arena season will begin.

Fully Curated Card Pool

This season features a fully curated card pool, hand-picked with Dual Class play in mind.

Updated Arena UI and Draft Experience

With Dual Class Arena returning, the UI has been updated to better support the experience. Both chosen classes are now displayed under your name during matches, Class Banners appear during the draft, and Hero Powers are offered first to clearly signal that you are drafting in a Dual Class season.

Events

Forging the Dragon Soul

From May 5 - 26, lend your strength to the final confrontation with Deathwing! This Deathwing comes from an alternate timeline where he emerged victorious and claimed the Dragon Soul for himself, so if the heroes of Azeroth are going to stand a chance they're going to need a Dragon Soul of their own, but this time with a little something extra. Help them obtain this mighty power and claim these rewards:

  • 1x Dragon Soul, Shattered (Golden and regular)
  • 1x Mage Pack
  • 1x Druid Pack
  • 1x Hunter Pack
  • 1x Paladin Pack
  • 1x Golden Cataclysm Pack
  • Raid Finder Card Back
  • Valor Point Coin

Ruby Sanctum

From May 26 - June 2, help Alexstrasza defend the Ruby Sanctum from attack and protect the red dragon eggs. Complete this task to earn these rewards:

  • 1x Druid Card Pack
  • 1x Hunter Card Pack
  • 1x Mage Card Pack
  • 1x Paladin Card Pack
  • 2x Tavern Tickets

Alexstrasza Returns to Darkmoon Faire Treasures in Her Classic Look

From May 5 - 26, Darkmoon Faire Treasures returns with a brand-new lineup of dazzling prizes, including a familiar and legendary face. Dragonqueen Alexstrasza, the Life-Binder and Aspect of the Red Dragonflight, returns in her iconic golden battle armor, now as a Mythic Hero Skin for Druid and Mage.

Step into the role of the Great Red Leviathan and face your foes with fully custom animations, from descending onto the board with a burst of red magic to rising from the Hero Portrait to deliver a magical dragon slash. Though renowned for her compassion and kindness toward all living things, Alexstrasza answers threats with unwavering courage and unleashes her draconic rage. Claim victory in blazing style as she unleashes a powerful surge of red dragon magic on your opponent when you win, or watch her magic power fade like the wind upon defeat.

Darkmoon Faire Treasures is our random pull system that rewards Pets, Mythic Skins, Signature cards, Hero Skins, and more. The first pull is free, and subsequent pulls require Runestones to purchase. Every pull guarantees a prize. As the prize collections in the Treasures booth rotate, prices adjust to match the value of the current items. Read more about the current value of Darkmoon Faire Treasures, as well as pull rates and odds.
