A glance at Bogarus

[Deathblob]

There is no point in taking Drain 1. Drain 2 is 40 free points. Also, try to get your Earth Mother up to Dom9, and it will last a lot longer in initial expansion.

And you can't take friendly fire damage from a frost brand because it only hits an enemy square. If you want a 3rd path on your god, I'd go with A for Air Shield. Use Spectral Mages if you have no other way to diversify into W.
