MMH5.5 - Heroes of Might and Magic 5.5

I've returned to the game after a long break - how can I check which version of the mod I have installed?
Is it possible to significantly increase the damage from Chaos/Summoning magic spells? (for example, via a school level multiplier). Caster heroes lose very badly to warrior heroes in long games (on large and huge maps).
When you're leveling up a caster hero and your strongest ability deals 1000 damage, while any stack of a warrior hero of a similar level deals from 5000 to 10000 damage (or even more), it becomes kind of sad and the desire to play casters disappears And at the same time, the caster will quickly run out of mana, whereas the warrior hero won't because their buff/debuff spells last over time.
Is it possible to release an additional mod that allows this to be adjusted? Or please tell me how to do it myself (though I probably won't figure it out)
