Blizzard revealed details today for Hearthstone’s newest adventure, and it’s got an Indiana Jones-like theme.

Titled The League of Explorers, the mini-expansion will add new cards and give players computer-controlled opponents with unique abilities to fight, similar to Curse of Naxxramas and Blackrock Mountain. The first wing comes out on November 12.

The new cards include a new mechanic, Discovery, which lets you choose to draw between one of any three different class or neutral cards in the game. You can see an example of it in the card above. One new card, the Golden Monkey, replaces your entire hand and deck with Legendary minions.

These Hearthstone adventures open up in wings, typically one a week. You can watch the trailer for The League of Explorers below.
