Five New Arena Achievements & Rotation Arrives in Hearthstone on October 28

Hearthstone's Arena mode is getting its usual rotation of sets and a new set of achievements that reward you with Tavern Tickets. Here's all the details on the upcoming set change, and a sweet reward for achieving 12 wins in the underground.

Quote From Blizzard

On October 28, with Patch 34.0, all ongoing Arena runs will end and a new Arena season will begin. The eligible sets that will make up this Arena card pool are:

• Across the Timeways*
• The Lost City
• Into the Emerald Dream
• The Great Dark Beyond
• Perils in Paradise
• Whizbang's Workshop

* Please note that Fabled cards are not currently included in Arena, but they will be added in a future update.

With the new season comes a fresh reward for achieving 12 wins in Underground: the Old Ways Ulfar Hero Skin. This replaces the previous reward Hero Skin. After unlocking it, any subsequent 12-win runs will earn you an alternate prize of 2 Golden Across the Timeways Packs. When Across the Timeways releases on November 4, all Arena and Underground pack rewards will update from The Lost City of Un’Goro Packs to Across the Timeways Packs.

We've also got the full details on the new achievements that are coming for Arena mode.
