[@Jangel13]I was trying to work within the existing framework.  Thus, I'm glad that you can't tell any functional differences.  As for artifacts, I suppose that I meant 'gifts of the gods'.  It could be anything that the deity might consider a worthy gift for their up and coming follower from a sword with a blade that is only visible to the wielder to a flying mount or armored gauntlets that allow extremely fast digging, even through rock.  When gods go up against each other through followers, if historical mythology is any guide, they usually use a combination of blessings and gifts to strengthen their chosen elite while all their followers get blessings.

Furthermore, the entire tree is merely a suggestion.  I am but a sideline idea man.  I do hope that part of it is useful at least.
