7th Interportal Tournament of HMM3-OFF: "Earth Magic"

I realized it won't be like this: I started a battle, and on the 3rd turn, the gorgon killed 3 rusty units?
And to achieve a result, do I need to use the battle repeatedly, i.e., replay it 50-100 times? In short, is there a chance to achieve a result in 100 attempts?

If the probability of the ability triggering is 10%, then the probability of it triggering twice is 1%, and three times is 0.1%.
That is, by simply repeating the battle, we achieve a result after 1000 attempts.
But, let's assume that there is a hidden pattern that, if known, can increase the probability of the ability triggering from 10% to 50-90%.
For example, the unicorn needs to move to a specific cell. Then, not always, but usually, the ability will trigger. Doubtful, but let's assume. In this case, yes, it might be possible to achieve the result in 5-6 attempts.
