Hey, the new Angelic Paragon. Nice!
I like how you build upon the spirit guide. I did have a quick question. The Astral State ability is inspired from the Dragon Magazine feat, that also gives a spirit guide, correct? If so, how do they interact? Can you have more than one spirit guide? If you get the same guide from both do the bonuses stack? It was just a queery of mine.
Overall, I think it's good. I like it.
My favourite is still the inspiration and history behind the names. It's like an Easter Egg for reading the thread.
