The next Hearthstone expansion is a murder mystery set in a location from World of Warcraft's latest expansion. Murder at Castle Nathria, based on the raid from Shadowlands, is coming on August 2. The set revolves around the death of Sire Denathrius, who was murdered at his own dinner party.

As always, this expansion will introduce a number of new mechanics and keywords. For the first time Hearthstone will get Location cards, giving you an advantageous boost while they're on the board, but needing a one-turn cooldown between uses. Blizzard says Locations will be a new permanent addition to Hearthstone, similar to Minions, Spells, Weapons, and Heroes.

Meanwhile, a new Infuse keyword will transform cards in your hand when minions die, turning into more powerful effects and even getting new artwork once they've become fully infused.
