That social hall / bar / nightclub idea I had could equally work as an extra upgrade on the Soul Creator.
Percentage chance of at least one summoned soul being the highest level available.
The downside with this is that it may lower the chance of summoning a high level soul until this is levelled up a bit.
I had another idea regarding the Soul Creator. Have the summoned souls arranged in order of level, left to right, high to low. Although it does let you get to know each character slightly when you need to click on them all, it would be nice if I could click on them until I hit my personal low limit for what I want on my team. There are some exceptions, like Combo______. I only have Comboflame unlocked so far, but he is great. I know that as more of the high level characters are unlocked, their level will become less relevant...
...which makes my idea moot. Oh well, it was a nice idea before my brain stepped in and ruined it.
