It doesn't work on unupgraded units, that's true. Another bug is the game crashing in the second Orc mission.

This topic is strange; please explain what it's for. :)?

Well, my specific example: when developing a hero, is it worth taking a specific ability/spell? What if it doesn't work as described?

Is it worth upgrading Griffins? (in case someone doesn't know?)

Unupgraded riders really don't increase damage from the charge. I think I got something wrong.

And about the Ice Storm... not only can it not be cast if an obstacle from the battlefield falls within its area of effect, but it also cannot be cast if its area of effect overlaps with the area of its previous cast.

And another question. I'm playing as Irina the Sorceress, and I can't get the Kirin Sword. It disappears when I load the game. I've tried everything - I gave it to a secondary hero, had that secondary hero fight several battles with the sword - it doesn't matter. I load the game, go to the hero's inventory - the sword is in his hand. I go to the dynasty weapons tab - it's not there (in an inactive state, since it's with the hero). I move it there - it disappears.

Does anyone know a reliable algorithm for how to save it? :)
