Before I waste any more of my hard-earned XP, I would like to know in layman's terms what you expect to happen.
From what you said, it seems to me that you think that either:
- The XP I make in Outerworld will be spread evenly among all the souls upon returning to the Sanctum.
- The XP I make in Outerworld is... wait... I don't have a second idea. No need for a numbered list. Maybe the XP is spread among all the other characters, but my main characters always end up with 2 XP. If I do 30 levels and have 1000 XP then return to the Sanctum and back to the Outerworld, my four active characters have 2 XP each. If I do 1 level and have 30 XP then return to the Sanctum and back to the Outerworld, my four active characters have 2 XP each. It is always 2, but as I mentioned in an unrelated post, there is no way of checking how much XP the other souls have without having them join my party.
So it returns to that problem. It would help in many ways if every character could be viewed fully from the Soul Creator page. Not just their image and spells, but XP, equipment, pet etc. It feels strange to have a game with many playable characters that cannot be accessed most of the time.
But what would help more is if XP earned remained earned. I still don't really get what is meant to be happening with the Soul Creator or XP manager or whatever. All I know is that Sanctum is eating my XP. If my first point on the above list is correct, then that is fine. I quite like the idea that all the characters I don't use can make more XP than they earn passively. But I suspect that you have a far more clever algorithm at work but somewhere in it there is a zero where there should be a one.
