Hearthstone Patch 10.0 Notes – Kobolds and Catacombs, New Card Backs, and More!

The new Hearthstone patch that adds all of the Kobolds and Catacombs cards to the game has arrived! Check out the new card backs and the patch notes below.

New Card Backs

Both Frostfire and Azeroth is Burning are completely new, while the other two are part of the Kobolds and Catacombs expansion.

Azeroth is Burning appears to be apart of a “Special Promotion” which is related to the next World of Warcraft expansion (likely a reward for pre-purchasing).

    “New repeating daily quest – Spelunker: Defeat 5 Dungeon Run encounters. Reward: 1 Classic card pack.”

    This is a new quest that can reappear forever like other dailyquest or is unique?.

      Curious minds want to know about the Spelunker quest, how long will this go on?

        It seems it is just one more Daily Quest, like all the others. Nothing special.

        Ben Brode: “it’s another quest added to the pool of random daily quests”

      Well, the “repeating DAILY quest” speaks for itself (there are no restrictions, like until the end of the month or for two weeks so it is more likely that it goes on forever………… or at least hopefully lol). It feels too good to be true, but Blizz has finally done it, a 1 free classic card pack daily.

        Um, it’s called specter… watch a friend win for a classic pack… So now there’s two ways

    I don’t understand the part of the change to the “concede” button.
    If I press”end game” it will tie the match?
    So I can never lose?

    It cannot be, so please some1. Explain it

    • NOC

      Yes, you can’t lose. And it is for friendly matches only.

      it says the change is for friendly challenges, so it won’t affect ranked games.

    • Sebu
      December 6, 2017 at 11:54 am

      It is written under the subcategory: “Improved reconnection and UI for Friendly Challenges.”. Which means it will only be applied to friendly challenges.
