Blood of Shadows introduces Shadow as a Blessing and a Subdomain. Since Shadow is a Subdomain of Darkness for Clerics, does that mean that Warpriests can not take both the Shadow and Darkness Blessings? The book does not mention anything about this.
If you're not a multi-classed warpriest/cleric, the existence of something called "domains" is irrelevant to you.
Alright, thank you. It does seem that about 80% of these questions involve over thinking things. :)
