Thx for clearing unit/hero stats , i cant check anything connected to games at the moment
But i can still check game files in notepad, and think about ways to make player curse those who made mod that is killing their nerves
Max of 600% you mentioned is a bit much but for it hero would must have 90 attack so not really an issue, but try to make it so it`s not limited like it was so far on +60att to enemy def, and everything above is a waste. Defense bonus on other hand should be reachable with your change to spell system and stone skin/magic spring 80% def bonus , belt of victor etc, but it will be really situational. This will make neutral stacks a bit inferior, but battles with enemy heroes will be much more fun, and just maybe you`ll finally make mod that is truly impossible to do with no loss (hero with 50 intellect and 3x cast , and your rage/mana stop regenerating after 20 turn so no resurrecting
And Q : how did you plan to implement Tomes of Might&Magic in game here ? As items, and if so will they be for hero, or companion, and will they be removable or like kids in tLegend when equipped with no way to replace them (maybe only to destroy it). In tLegend it was nice idea, you get a kid and if it soothe you great, but if you play warrior and get intellect/mana bonus kid tough luck no adoption available
What i mean to say is if you acquire 1 tome(kid) next gets available after 10 battles and it`s random, or you can buy one you wish for 100.000 gold but next will cost 200.000 and 4th 300.000 or you just play battles and get some random like with kids.
Then you change whole army and drop all tomes and start over and then again every next cost 100k gold more starting from 0. I guess that would be tricky to make functional in game, but i thought how will player use this new tomes you want to import. In tLegend it was doable since there kids already had system working and you just made bunch of new kids and give them HoMM3 heroes images and it was great. But how you plan to do it for AP/CW ? No wife to surprise you every 10 battles with new addition to family
