It takes 4-5 hits because the ability can theoretically activate in the fourth and fifth rounds. However, on the second turn, on this specific map, it is impossible to conduct such a battle, in my opinion. The Rust Monsters destroy 2 of our units each round. Therefore, in the 4th round, only the Gorgon will remain, and the Rust Monsters will make the first attack.
