Very interesting! This domain has some unique mechanics built in to it that definitely make it stand out from the usual WotC clerical domains. The one problem I personally have with it is that it gives proficency with heavy armor and martial weapons, but have a Divine Strike at levels 8 and 14 like other "martial domains" like Forge, Tempest, or War do, and neither does it have potent spell casting. I do respect that author's decision to deliberately try to do something different, but I personally worry that it might fall behind a bit in terms of combat power without either of these two features. If you want a clerical domain that tries something new and different from the standard WotC domains, then definitely pick this up and give it a try!
