Call of Cthulhu is probably one of the most well known games in all of gaming, second in name recognition only to D&D. It is, however, not played nearly as much as many other games with less name recognition. Despite this there are indeed RPG dice made specifically for Cthulhu.
Call of Cthulhu makes use of the standard 7-dice set, a fact that many people who have played Cthulhu are unaware of. The vast majority of the game is played with only percentile dice — these dice handle rolls for every skill in the game, and the well-known sanity checks.
Dice outside of the percentile are used only for three things:
- Rolling initial stats
- Rolling for sanity loss
- Rolling for physical damage
It’s probably pretty safe to say that 95% of all dice rolls a player makes in Call of Cthulhu are the percentile dice, and perhaps 70% or more of the game master’s rolls are percentile as well. But there are just enough occasions when another die type is needed that a full dice set must be at hand.
Call of Cthulhu Specific Dice
While any 7-dice set can serve the purposes of a Call of Cthulhu game, the unique atmosphere and mood of Cthulhu prompts many players to have special Call of Cthulhu dice sets. A couple of manufacturer make dice specific to Cthulhu, most notably Q-Workshop.
Q-Workshop makes a line of Cthulhu dice that are a 7-dice set with Cthulhu designs printed on the face of the dice. These Cthulhu dice are available in a variety of colors (even pink), but the most common and popular are the black dice with green print.
At one point Q-Workshop even made glow in the dark Call of Cthulhu dice, which followed the black & green design but using glow in the dark in on the dice. These dice were printed as a one-time limited edition set (and sold for over $40 per set!) and are currently out of print. Q-Workshop has not announced any plans to reprint the glow in the dark Call of Cthulhu dice set, though they still have the set listed on their website, so perhaps they’ll revisit it at some point.
Q-Workshop is not the only Cthulhu dice manufacturer. A German dice manufacturer has released a special Call of Cthulhu dice set called Arma Ctuhlhiana. This non-standard dice set includes 3 6-sided dice and no d12. The d6s (three are used to roll stats) and d20 have an elder sign printed on them.
It’s entirely possible that the d12 is not actually used in Call of Cthulhu. I can’t think of any instance where it comes into play: if it does, it is only as a sanity loss die, but I can’t think of a creature that yields a d12 sanity loss for a failed roll.
Unlike the opaque Q-Workshop Cthulhu dice, the Arma Ctuhlhiana dice are a mixture of opaque and translucent material with air bubble in the center, giving them an appropriately yellow-green Cthulhu look and feel.
