Two knights, a Priest and Pegasus Knight and I'm done in one turn... any help?
I am going to guess that I am doing everything wrong and really need some tips.
Depends on the enemy, but I wouldn't take 2 knights with my pegasus knight if your party size is restricted to 4 units. Rather take one knight and either two healers or one healer + an apprentice. I would go for the latter though since it can be dangerous not to have any magic attack units in your party as some units are totally immune to physical attacks, such as the werewolves which are encountered in the empire saga.
Also, consider buffing your own units with defensive spells and softening up some difficult mobs with magic attacks or magic summons. The spell "magic armour" works wonders in this regard. Usually it can unload at least two attacks on a front line target before it gets killed. Then you can quickly get rid of that unit when you attack with your main party :D
