With the weekly maintenance came the patch for the Hearthstone expansion Kobolds & Catacombs, which has since been activated. Go on a treasure hunt!

Here are the most important facts again:

• Logging in after the launch gives you a gift from Blizzard in the form of 3 free Kobolds & Catacombs card packs, plus a random Legendary Weapon.
• Treasure hunt: A FREE, repeatable, single player experience that has everything you need!
• Legendary Weapons for ALL nine classes (as collectable cards)
• New keyword: Recruit
• Two new card types: Magic stones and Unidentified items
• All in all 135 new cards for your collection!

Hearthstone - New Daily Quests

• There were three building on each other Treasure hunt quests each with a card pack of goblins & catacombs added as a reward *.
• Complete a treasure hunt with all nine classes to get the back of the card "King of the Candles" to obtain.
• New Daily Quest - Speleologists: Defeat 5 enemies while hunting for treasure. Reward: 1 classic pack.

There were also some improvements and adjustments in the interface and the arena. In the arena, Blizzard was busy tinkering with the probabilities that certain cards would appear. The intro video was also replaced by the short film "We are Hearthstone". You can find the details below:

• Reconnect and friend challenge UI have been improved.
  • A new "game paused" notification will show a countdown while waiting for the opponent to reconnect.
  • When a player reconnects, the time for their turn is reset.
  • The game menu now shows "Quit Game" instead of "Surrender". Selecting this option ends the game in a tie.

arena

• Adjusted the frequency with which cards show up in the arena when building decks.
• Note: Neutral non-basic servants from the classic set form the basis for the frequency of appearance:
  • Basic / classic neutral servant: 0.5x
  • Non-basic / classic neutral servant: 1x
  • Neutral servant from the latest set: 2x
  • Basic servant of the class: 2x
  • Basic spells of the class: 3.5x
  • Non-basic / classic servant of the class: 2x
  • Non-base / classic spell / class weapon: 3.5x
  • Servants of the class from the latest set: 4x
  • Class spell / weapon from the latest set: 7x
• As part of our efforts to bring the class balance into line with the arena, we regularly make small adjustments to the frequency of certain arena cards.

There were also a number of bug fixes:

Localization

• The card text of Elekk the King now says that a card is drawn and no longer that it is put into hand because the functions differ.
