At the beginning of month 4, two pairs of enemies arrived almost simultaneously, with only a couple of days between them. One was killed by my cunning units; then, I weakened and killed a tough demon, although it was difficult. Immediately after, a demon and a gnome with even more units appeared, but I got lucky; they came through the same portal, and the demon killed the gnome. The demon is Letos, with 38 spells; a direct fight with him ends in fatal losses, and I don't have many resources left for cunning units; I spent almost everything on the previous pair. It seems I'm at a dead end; if I manage to deal with this, the next ones will definitely kill me. I made a big mistake by deciding not to train a Stronghold unit when I had the opportunity and resources; the lack of spells is now a critical problem. I'll have to replay the last third of the game, but I'll put it off; it's a very tedious process. I wish I could reduce the number of units and stats of the enemies, even just a little; it would be more enjoyable.
