The Dawnflower Anchorite is a super cool prestige class that I really like. However, I am quite curious why, of all the things it can progress with its Focused Class Feature Credence, bloodline and/or mystery aren't on there. It's just odd to me, since there's a solar bloodline and mystery, and it would seem natural and thematic to have those included, particularly when compared with some of the other random items on the list.
Is there some rules thing I'm overlooking, or some reason that would be overpowered or otherwise inappropriate? Because otherwise I plan on houseruling that they'll stack.
That is unfortunate. I would go ahead and houserule it, especially in the case of the Solar Bloodline as it is tied to the Dawnflower after all.
The one thing that really bugs me about this otherwise stellar prestige class is the need to have the Divine Light credence if you want to use the Solar Invocation indoors or below ground. I just houserule that credence should be written into Solar Invocation automatically. The PC already loses a level of spellcasting. Why should it waste a credence to make SI useful in such situations?
