Huvrag is too strong. No race has a 50% magic growth bonus unless it's tied to education.
It doesn't make sense for Shagrat to get a bonus for losing an army, as this can always be arranged, but it's not always possible to complete a battle without losses.

Huvrag is an Orc; he only uses magic as a supplement. The balance isn't quite right yet; it needs to be adjusted when all the heroes are ready. But feedback is always welcome.
Regarding Shagrat: the number of enemy losses is also a factor, which I forgot to mention (because there are weeks when creatures are weak, and you can significantly increase their attack power). Yes, this small feature with losses can be removed, or increased to a percentage of the entire army.

Most likely, the "with losses" condition will be removed from Shagrat, and the number of enemy creatures killed will be increased, depending on the time in the game.
For now, I'll weaken Huvrag to 3 per level, instead of 2.

I'll give Shagrat the following condition: If the number of killed > absolute day * 4, then +1 attack. This needs to be earned every week.

All that remains is to determine the hero's race:
-Can steal enemy units at close range using a custom ability.
Formula: Can steal (8 - creature level) creatures for every 3 levels of the hero. If the unit is larger, it cannot be lured. The largest possible unit is stolen. In this case, a unit is considered to be a combination of all identical creatures.
Close range - 10 cells. The ability is activated on the next day. Only one hero/object can be stolen from once a week.
