Food for thought.

As an example, I'll write about my own experience. I was playing a very interesting single-player map where an area rich in artifacts was guarded by a hero of maximum level with stats of 100/100/100/100 and an army of 999/999/999... black dragons, and he was called "The Law." It was assumed that it was impossible to defeat him, and you just had to choose the right moment to avoid encountering him. A Necromancer with a pair of vampires and a fight to the last turned out to be no match for such a monster. When raising the dead, the unit's hit points decrease to as low as 1, and when a pair of vampires reaches this level, it becomes almost impossible to kill them. The dragon hits him with tremendous damage, but one vamp still remains, counterattacks, and there are two of them again. And the vampires themselves attack the dragons in such a way that they attack each other and burn through each other. The battle was epic and allowed me to see new aspects of the game mechanics in action, although in a multiplayer game with a live opponent, it is unlikely that you will achieve such an effect.
