Hmm, how does the random map generator (RMG) work? It uses a seed during generation (as stated in the scenario description). What if we create our own map generator or a map database based on seeds? That is, you enter, see the seed, and view the map in a program. After all, the map creation algorithm is already known.
Next, we know where the monsters are, we know the entrances and exits, it's time to write a battle simulator! In the simulator, we sketch out a plan for further actions (the simulator must have undo/redo functions), we repeat the same actions in the game, and voila, there will be no more stupid defeats.
And what is the result? Our own casual heroes with Blackjack and other perks. It's a disgrace!
