Finally, the hero's physical strength actually means something! With a small army, even a level of 19 is very helpful!

And what is that "Honor" spell for the water creatures? I see that Anton can't master it; it's not even in his potential development.
And what does "axe," i.e., "Cleave," do – is it effective? Is it worth taking? It would be nice to cast it on Radiant Beams and hack away at the enemy in all directions!

I'll answer my own question – it's worth taking, because if an enemy unit dies, the victorious unit gets an extra turn! I like it! As for "Giant Killer," it's hard to see how it works, but it only deals 10% damage to large enemy creatures. So, you might not even notice it.
