I recently picked up a set of Q-workshop's Arkham Horror dice, I really wanted some special dice for Helldorado and didn't need enough to justify a custom order. Since Helldorado only uses five dice ever this was the perfect set to pick up.
As you can see from the photos the dice have a "evil" feel to them that fits with the factions I've chosen to play in Helldorado. The bone colored die are easier to read than the green and black version.
Overall I'm happy with my purchase the died are extremely well detailed and roll nicely.
