marcinl0, I still dont get your point, so I have to ask you something. Are you sure you know the basics of KB? Can you tell me how you can reach 300-400 mana with your hero?
This mod raises your mana with 21 in difference with the original rules. Again if you want hardcore version, play with the original rules and dont raise your skills on level 3, I have done this, playing only with skills level 1 and 2. I will not change anything you suggest, because my objective was different than yours (which I still dont understand). The only thing that comes in my mind is that maybe you think your hero can raise her attributes with 18 each, or adding 90 more mana and rage (these are the new values, not extra bonuses), which is not the case, read again the description.
I will change the morale file of the units, removing the neutral creatures bonus

I wanted more morale for trolls and cyclops and I didnt count that dragons are still neutral and they are buffed by voice of the dragon skill. Just download again the file and install the mod. It doesnt need a fresh game start.
