Gambler's Cards

Pay the Gamemaster 100 gp:
You and the Gamemaster pull a card from a deck of playing cards. If you have a higher value, you win 20x your card's value in XP
or GP. If there is a tie, you earn 30x the
value in GP or XP, and the Gamemaster
keeps this Artifact. If the Gamemaster has
the higher value, he keeps this Artifact.
