Blizzard has announced the next Hearthstone expansion, Kobolds & Catacombs.

The digital card game’s third expansion of the year will add 135 new cards that channel classic D&D adventures while introducing new mechanics and keywords.

The standout from the announcement is that each of the game’s classes will be receiving a new legendary weapon card. It’s the first time classes such as Mage and Priest have been given weapons in the game, although some are designed to offer bonus effects rather than simply smack enemies in the face. For example, the Mage weapon, Aluneth, allows you to draw three additional cards at the end of your turn.

Kobolds & Catacombs will also add a new single player mode, Dungeon Run. Similar to a video game boss rush, players head into a dungeon with a small deck of cards and must beat a gauntlet of opponents to earn treasures and add cards to their deck. It’ll launch for free alongside the expansion.

While no specific release date has been announced, Kobolds & Catacombs will launch in December.
