using blurpsl's event and panadell's event i can get my character's stats up to 250 ( I don't go higher than 230, because anything over 250 makes it go back to 0) no save game editing needed. I just don't change any stats on the create a ruler DLC, change them in game and voila, big pimpin.
Yea, I noticed that, trying to figure out how to fix that as my current King is at 0
