Big fan of both.

Maybe the offering command would allow you to deposit items, or penned scrolls, or carved things, etc. at your deity's shrine. Might even be cool to allow those things to be picked up by others, with the obvious potential for immortal/follower retribution.

Maybe the second one could work a little like last name does. A small RP reward that the character would come up with a few sayings and then they would go into effect after the character gets recognized.
