"You receive substantially lower amounts of edgepoints from immxp than any of the other methods (depending, of course, on the amount of immxp you get). On the flip-side, there is no real limit to how many you can get, so over the course of a long-lived (age-death-type) character who interacts with several imms, you might see more edgepoints from immxp than other (capped) sources."

I'm sure there's an alternate universe where this might happen lol. I think you'd have to really go out of your way to try to get every imm you could involved in your character though. A quick check through some titled, tattoed, leader-types shows that over 4k is kinda bizarro-world rare and probably requires a Baer follower.

Would imms react positively to mortals randomly seeking them out to chit-chat? I've only really tried to interact with Imms for my cabal, tattoo/religion and empowerment.
