That precludes me from getting any reward.

I write a decent role for the Imm exp then I play.

I don't get rewarded, ever, no matter what I do so I've shied away from trying.

The effort is not worth the reward for me. And I think you are a masochist. :) I was empowered three times by Thror, and didn't get any Imm exp on any of them. That's just not fun for me.

There are a lot of neat edges, but I basically have to reroll and rank to 25 on a bunch of different characters to play them.
