Better than two Natural 10s.

Rolling a 10 can be good. It's usually enough to get you through moderately difficult encounters - picking a lock with thieves' tools; chatting up a whore at the local tavern; hitting a peasant who has no armor.
But a Natural 20? That's when the good stuff happens. Critical successes. And, if you have a kindly GM, you can change the world in which you are playing.
Now, that's what *we're* all about.

In our prime.

If you will look closely at the dice arranged so artfully along the spine of our model, you will see that they are all prime numbers. Or are they?
That entirely depends if you count '1' as a prime...
