Impossible Warrior - no losses?

[Arilian]

For me it is still pretty hard, but at leas i can kill leathal armies except a few really irritating kind if enemies.
I am at the 100th battle atm. (no losses)
Money is finally not a problem
Tried out Assassins and for me they work better than snakes (i got not snake boosting item) bat not a big difference anyway.

Lots of shamman in a lethal enemy are really the pain in the ass, they have TONS of hp and they can kill any of my units with the axe spell.

Can i somehow guide the lightning orbs to a spcific enemy?
