"Weak demons"??

On the first map, only a psychic will attack you. There might not be any level 10-11 creatures on the second week. In short, the point is that on the second week, there are too few summons, firstly, and secondly, in the army at this point, there are at most 5-10 succubi, and if you're lucky, temptresses, but again, there will be too few summons. And if it happens that you have to fight in an open field, where there are no trees or bushes, you might not be able to block the neutral creatures' movement. It's not even worth trying against flying creatures. And you can't outrun all melee creatures either.
