Hearthstone has taken the world by storm thanks to its slick gameplay, easy-to-learn-yet-difficult-to-master rules and mechanics, and its constant expansions and updates. Today, at BlizzCon, Blizzard announced the latest expansion for the game, the Dungeons & Dragons inspired/themed Kobolds & Catacombs.

The most important feature of any collectible card game is how it sets itself apart from other, similar games, and more importantly, if the game’s developers can continue to introduce new and unique mechanics. Since Hearthstone‘s next expansion is D&D themed, it will introduce treasure chests and loot to the game. Players will have to bash open the chests to get at the loot, but it will be well worth it, since what lies inside might just be some of the most broken and overpowered cards in any CCG. Not only will players be able to summon (and destroy) treasure chests, but many cards introduce the keyword “recruit” that lets players summon a random minion directly from their decks.

Kobolds & Catacombs will finally introduce new legendary weapons, one for each class. The first weapon that was shown off during the Hearthstone panel was the Priest’s Dragon Soul weapon that lets players summons a powerful dragon with five attack and five health  after they play three spells. The second weapon was the Mage staff Aluneth that lets players draw three cards at the end of their turn. I told you these cards were broken. But, weapons aren’t the only broken cards in the expansion, as players will also be able to use three different unidentified item cards. No, seriously, that’s what they’re called, because players don’t know what these items do until they’re drawn. Kobolds & Catacombs will also come with special class-specific spellstones that can easily make or break a match.

What is a Hearthstone expansion without new minions? Well, Kobolds & Catacombs comes with Guild characters who spawn treasure chests and focus on the recruit keyword. But, the Guild isn’t the only potentially game-breaking set of cards in the expansion. Rin, the First Disciple is potentially the most powerful card in Hearthstone, if not any CCG, because she gives players a set of Seal cards that summon demons. Once gamers play all the Seal cards, they can summon Azari, the Devourer, a demon that destroys your opponent’s deck. Yes, you read that correctly. Also, since the expansion is called Kobolds & Catacombs, it comes with a bevy of Kobold minions to summon and slay.

New cards aren’t the only additions to Kobolds & Catacombs; the expansion will also introduce the Dungeon Run, a special rogue-like single-player game mode that tasks players with fighting random boss monsters with limited decks. Each time players defeat a boss, they gain new rewards, some of which are too overpowered for regular gameplay, but whenever players lose they need to start over from scratch. Only the players who make it to the end of the Dungeon Run will get the best cards; the risks may be huge, but so are the rewards.

Hearthstone: Kobolds & Catacombs looks extremely promising and brings in mechanics I never thought I would ever see in a CCG. I can’t wait for its release, and neither should you. Plus, if you were lucky enough to either visit BlizzCon or get a Virtual Ticket, you will gain a special gold edition Kobolds & Catacombs card.
