Keeping army units alive in campaign (chapter 5+)
I'm not sure what I'm doing wrong, but it seems like the enemies I'm fighting in the campaign are much tougher than my line troops. I can build knights with great defenses, but they always start with 5 hit points.
Specifically, the point at which I started having problems was the troll with the dragon. He could one-shot my knights, leaving my sovereign vulnerable. Once my sovereign dies, I go back to the city, rebuild, and kill him on the next try. And almost every fight after that has opponents that hit that hard. Archers worked a little better since I can always keep them out of range, but the point where I gave up tonight is when I lost two armies to the demon that hits the party with a 3x3 aoe. I can't keep allies alive through that when the allies are always level 1.
Did I miss something? The one thing that's surprised me in the campaign so far is that it hasn't let me build anything that lets me do research -- they all seem to be quest rewards. I've maxed out the armor and weapons I can put on guys, but I can't get them any additional health. I haven't been using the NPCs I was given at the start because they didn't look like they had combat skills, but I'm wondering if their health makes up for that.
