Skirm is a card-and-dice dueling game found within the world (and every copy) of Vantage. Each player rolls 6 dice, selects 1 card to play, uses their card's ability, and gains points by comparing the quantity of each skill type to the opponent and leveraging their card's scoring ability.

While intended as a game-within-a-game, Skirm is a fully-playable dueling game for 1-2 players on its own.
