Yeah, but alongside with Valen I have all the tactics challenges installed, and I think those two mods compensate each other, though I don't really care about such things as balance as long as I enjoy the game process.
Anyway, thanks for the advice, I think I'll just have to complete the keep beggining from the lowest stages(Killing Demogorgon) and then proceeding to the upper floors.I don't care much about the way I'll complete the challenge,since this is by no means the first time I play the game.
