Hearthstone: Kobolds and Catacombs

Kobolds and Catacombs is Hearthstone's seventh expansion. Featuring 135 new collectible cards, the expansion released on December 7, 2017 in the Americas region and December 8 in the Europe and Asia regions.

Hearkening back to the roots of classic fantasy and dungeon crawlers, the expansion sees players venturing deep into dark dungeons and winding catacombs in search of treasure and loot, encountering monsters, traps, rival adventurers, and — above all — slovenly, candle-obsessed kobolds along the way.

The expansion introduces the Recruit keyword as well as the Dungeon Run, a unique single-player experience where players defeat increasingly more challenging bosses using a deck of cards they acquire along the way.
