One dwarf in 4 has D1. One dwarf in 10 has another random. Out of these, only 1 in 4 will have another death random. So its 1/4, 1/10 and then another 1/4.
Somebody who doesnt such at math as much as I do can tell us the chance of getting such a mutant.

I've seen one D1F1 dwarf once in my life. Counting on a D2 dwarf is not something I'd advise.

But were Allfather to become cheaper, I'd probably pick Earth over Astral, of course... I hate starting with no astral, but Vanjarls really need at least a minor earth bless. And Earth is one of the best paths for an SC, too.
