I suggest introducing the following elements into the game: the Valley of Death, the Mirror of Time, and the Judgment of Fate. The Mirror of Time is located in the Valley of Death, and upon visiting it, the Judgment of Fate occurs (it determines whether the hero has committed more good or evil deeds). After the judgment, a verdict is delivered: the hero's level increases by five points (if good prevails) or decreases by five points (if evil prevails). For "light" heroes (humans, mages, elves, etc.), good is defeating "dark" neutrals (skeletons, zombies, devils, demons, etc.). Evil for "light" heroes is destroying "light" neutrals (gremlins, djinns, angels, etc.). Good for "dark" heroes is destroying "light" neutrals (angels, gremlins, djinns, etc.). Evil for "dark" heroes is destroying "dark" neutrals (devils, demons, skeletons, etc.).
Once you enter the Valley of Death, you cannot return!
The only way is to approach the Mirror of Time and undergo the Judgment of Fate! You cannot turn back halfway!
The Valley of Death and the Judgment of Fate can be seen as a kind of chance for a losing player. Because if a player is doing well, they are unlikely to risk their hero. Only someone who has nothing to lose might dare to test their fate. Therefore, the reward (or loss) can be so great (tragic).
Also... the Valley of Death can only be visited, for example, from level 20 onwards. This is to prevent players from taking a newly purchased hero there and gaining a significant advantage at the beginning of the game.
