For future reference: The game doesn't seem to mind when the files are nearly empty. I left the important tags in, and removed everything else. It worked regardless.
I know that Character leveling is disabled in Multiplayer, but is it possible in Singleplayer?
~Edit~
I'm seeing stats with numbers assigned to them inside the OnLevelUp tags. Is this the probability of that particular stat being picked? If so, would setting all of them to 0 essentially nullify the effects of leveling up?
Is it possible to use a negative range on attacks without disabling the game?
What specific impact does Aptitude have on Hero training cost? Percentage or otherwise.
(I realize I'm asking a good number of questions, and I apologize. I should slow down and eventually let up once I feel I understand enough.)
