Loving the ideas. For the holy magic you will be adding, will it be restoration magic? Or will you put it under several trees forcing Seraph classes to take on a more "pure mage" build (exception being his angel blade of course)? Also I have some ideas for the new spells you could add. First of which is teleportation, either teleport to cursor, a hold, or to a sanctuary place if you add one in. Second I was thinking having a smite spell, being able to completely destroy things with a holy ray of light (or make it a touch spell) but only if they are quite a few levels lower than you and do not pass a check of sorts, if they pass the check or are a higher level (or a boss) it could just deal damage instead. I feel like this one would really make it feel like you are slowly becoming an extremely powerful being, especially if you also use a mod that delevels the world. Another I think would be cool is a passive effect of when you ascend, that when your wings are out in your ascended form, NPCs that are below your level should pass a check to decide rather if instead of attacking you will just flee in fear. However that might be a little script intensive.
