Humans may dwell here

I created my own blessing system back then, as you might remember, but there are still some challenges in terms of implementation... You need a priest/cleric class, you need a lot of like-minded people in the team, you need to visit temples, etc. Perhaps passives, like Revan's, are still better, at least they are more convenient, even if they are not very realistic.
Coming up with abilities, like Ples's, is still a lot of not-so-simple work. Perhaps it's only worth taking the system of righteousness from there (although, in my opinion, Ples had a bit too much "monitoring" of his followers ;)).
