MMH5.5 - Heroes of Might and Magic 5.5

Not sure what 200% bonus means. Do you mean if the creature has 200% bonus damage because of higher primary skills?

167% damage from a regular successful attack, and 200% damage – from Critical Strike (x1.2 instead of x1.1).

I put the exe file, as well as the settings and the patcher I used, here.
I didn't really test the game for stability; I just applied 0.0 settings, checked that there were no crashes in battles, and thought everything was okay.
Maybe I'm wrong, and there are really serious problems somewhere that I didn't notice?

0.1 ATB for the mass spells is because of the hardcoded issue. There is no way you can put 0 value. It crashes the game and 0.1 is the lowest possible.

If 0.0 causes problems, have you tried very small numbers like 0.01, 0.001, etc.?
