I'll take a look at it too, however, I'm more interested in another thing:

Gorgon, I see you made the Vis, vesa, sorry, forgot (really), that's supposed to be an evil guy and all. I like however the "bastion of competence" guy so much that I intend on using it as a kind of aligment-based holy warrior. While it's quite easy to adapt the aligment things to be from another aligment, what are the specific abilities you would suggest it I wanted to use good, chaos and law versions too?

Also, I think I don't quite get the reason for invocations. Besides for power, and balance, and being a cool mechanic, what the reasons for invocations in this class?
