I want to be doing that, but I'm putting up a lesser version of the whole thing with less automatisms, just so I have something that works. Problem is, I can't really see it working. I have checkboxes for every spell or temporary effect (like charging, or wearing a buckler while fighting with a 2-handed weapon)
and I can decide which are active when an attack goes. I can have a slider for power atttack, a field misc bonuses; I still have no way to say hey, if more than one effect gives me the same bonus, understand it and give me the largest one only.
