7/100 -- not a very high probability
By the way, the weakness of magic lies in the high magical defense of all troops. This system used to be better. Now you even see 80% (!!!) damage absorption :(.
P.S.: Yes, I also love single-player. Although, I looked at Heroes 6 primarily for multiplayer, so as not to "spoil my appetite before the meal" with the campaign.
