The Arkham Horror: The Roleplaying Game Dice Set is an essential accessory for those resolute enough to stand against eldritch forces. Whether you are fighting to save the world or struggling to keep your sanity intact, every roll counts. The official dice set includes 18 six-sided dice, 12 in black to fill out your investigator’s dice pool (or that of a titanic eldritch monstrosity if you’re the Game Master), and 6 in green to use as horror dice when your sanity begins to slip.
