I don't quite get what you're saying, here. As far as I know, the mana burning drop-down menus under the HP/MP Usage tab are what control the buffs specified in the mood setup tab. If I have 100 max MP, and I have one buff that takes 1 MP to cast in my mood, and I specify mana burning to start recasting at 85%, and cast down to 50%; if I have all that, when I auto-adventure with Mafia, it won't cast the buff until I regenerate to at least 85 MP, and then it will cast the buff 35 times. It will continue to repeat this behavior until I have (by default) 1,000 turns of the buff queued, and then it won't recast the buff until I run below 1,000 turns. That's just what I've observed through experimentation with the program, I don't know if it's supposed to work some other way, or if there's some underlying principle behind the mechanism that I haven't divined.
