Dom 9 or Dom 10?

[Aleph]

Depends on your model. A gorgon can probably get by with 9, since it's part of a compound defense. A prince of death probably wants 10, and enough death magic to boost fear radius a bit as well.

For me, the choice isn't between 9 and 10, it's more between 5/dormant or imprisoned and 10/awake. Once you've gone that far in your concept, you might as well see it through.
