Battles with neutral creatures.

Everything is correct. When you feel there's a chance, you eliminate the enemy, sometimes changing tactics if the first attempt doesn't work. Sometimes it takes 10-20 attempts. But sometimes you immediately see that winning is impossible, unless it's by chance. For example, unlike in the third game, it's impossible to defeat a Crusader with a Fairy in the fourth (I won't explain why). You can rely on skill, but not on luck. Perhaps that's why difficult saves from other players aren't always achievable – sometimes the player is helped by chance (randomness) that simply won't happen to you. And besides, your own task is more interesting – the one you're working towards yourself, rather than the one someone else is leading you to. Now I often make saves, and in the case of an interesting battle, I sometimes replay it, changing tactics. But I've also noticed something – if the first victory was very impressive, even if it was by chance, then when repeating the battle, the result may be worse – it feels like the AI learns and also changes its tactics.
