DIG

From BoardGameGeek:

The hill hides many treasures, and all it takes to collect them is to grab your shovel and dig! Well, maybe not as these aren't the only things the hill hides; creatures and traps await, so the tunnels that you create might lead to either wealth or despair. Delve into the hill and gather ten gems to win the game! Take some risks, press your luck, hire recruits to dig deeper and win favors of companions such as the knight, wizard, scout or hunter to protect your collections from the many creatures - thieves, skeletons, orcs, and more - and traps hidden in the hill. DIG finds its path between adventure, strategy, luck, and resource management. In this card-driven game for 2 to 4 players ages 10 and up, fun meets strategy, luck meets role-playing and fantasy meets pixel art design within 20 to 45 minutes.
