I had a GM who purchased a "Chessex pound-o-dice" that had white dice with red flecks in it, which he claims is, "the blood of players I have killed in the game."
I don't know about all of that, but I thought that "blood splattered dice" would be interesting to have. If you do a Google search for, "rusty dagger blood splattered dice" it shows someone who used acrylic spray paint to 'blood splatter' their d6's from a zombie game.
I've bugged Chessex about marketing such a product, they did not seem interested.
It takes time to go from 'cool idea' to 'I can sell this to you today'. So an idea I would have for Paizo is a Halloween accessory package for 2013 that would include "blood splattered poly dice." Maybe this would be part of a zombie campaign as a recommended accessory thing. People would likely want the dice and other 'cool stuff' and not the campaign, and I think your campaigns are just books without additional accessories.
I could 'blood splatter' the dice myself, as you can see from the picture, but
1) Would that impact the rolls? That would suck very badly if I literally jinxed my dice to not roll random.
2) Even if I could scientifically prove the paint has no impact, would it bring up the question of the dice being loaded in my favor?
3) How long before the 'cool blood splattered dice' becomes 'messy dice with red paint chipping off?'
Buying dice manufactured that way makes the problem simply go away.
If Chessex can make dice with swirly color in it, or white dice with red flecks, I'm not clear why 'bloody dice' would be such a big deal, and the people I talk to at the game shop seem to think that would sell like crazy for a Halloween special. Maybe this could be part of a 'minis' package? A larger gore-fest package? I don't see Paizo making *just* bloody dice, but as part of a larger GM 'must have' accessory kit? "Bone dice" just turns up D6's, and poly dice like that would be crazy to manufacture.
So I'm not sure how this could be packaged as a larger, "Must Have" set, but it is something I would love to see and purchase from Paizo.
Thanks!
