So, I've got a player desiring to play a lightning-themed cleric for Extinction Curse. I thought the natural fit would be Gozreh and he could have left the hermitage of blessed lightning as they started to go down bad paths. Then I realized that Lightning is listed as an 'alternate domain' for Gozreh in Gods & Magic, meaning it is not an option until 4th level and then only after taking the Expanded Domain Initiate feat. Does it make sense to allow members of that particular hermitage to have access to this domain from 1st level? I wonder if I should come up with a specific background for him that might grant that feat instead? I get that it's a 4th level feat, and I understand it is that way because it ADDS a domain to the character - I'm just trying to give access to lightning as his main domain.
I actually realized after posting this, that I could treat the hermitage as a splinter faith, and use the associated 1st level feat for this use. Now I would just need to determine what non-gozreh domain the hermitage would venerate.
