As for the portfolios, I think each of the submitted gods have portfolios that at least match many spells. However, people could arrange them in a set order, for example, 9 words, first three more important, second 3 less and 3 lesser, in order to assure a good alotment of spells (with the first 3 which will find many descriptors hopefully), and the flavour of a nice portfolio at the same time =)
Take Rathan's character for example, perhaps earthquakes is not something you'll find in many spells (just in Earthquake!), nor lava. But Fire destruction and Evil (combining Hatred and Revenge) will surely get you access to tons of spells.
I'm just thinking out loud here though.
This is good thinking. Also, I just used 2 descriptors as an example - it could certainly be more (just not all, lol). Lavaria could indeed, for example, get fire, earth (lava) and evil, as you mention or some others that Rathan thinks are appropriate.
