I'd like to know whether Effigy's Resentment or Gift from the Machine have any story impact, myself - like are they even acknowledged? I generally can't bring myself to get either in a playthrough, but if they don't even earn a mention, I might console them onto the character I'm playing now before importing.

 

And what about Mental Prowess, from the Llengrath encounter?

 

Yes, there are most definitely references to this in the story and at least one sidequest. I don't remember if the story comments on who you sarcrificed but the sidequest I saw just reacts to if you sacrificed someone at all.
