Did some looking around. Mafia does have combat-logs in its sessions folder.
Those are definitly useable, as they record item gain and loss (ie toast) heal and damage (medical systems, and normal attack) and meat gain.
Only problem is, it does not record deleveling. However, seeing how this is a single parameter out of many, it can be assumed from the others.
Which makes my question completely different. Anyone know where can I find a parser?
EDIT:I have wrote a parser myself for this particular problem. The log do not show frequency of familiar attack either, which is one variable too many to get a solid conclusion.
So the questino still stands, how can I get ALL combat parameters from a battle? Unless of course Nightmist have answered this question and I am just too out of date in ash scripting to understand it.
EDIT:EDIT: Going over the parsed data, I have noticed that the damage range of the "you lose x HP" statements is huge (I am talking 1-10). Now I am not sure about fumble damage calculation, but is it possible that KolMafia treats the damage done by your familiar the same way it does to damage done to you?
