From difficult to select units on the map and hard to target units in tactical combat to a rash of game crashes, this is not the most stable game ever produced. The 1.02 patch helps somewhat, but it's still more unstable and quirky than you're probably used to. You've been warned. Champions and Followers Your army is composed of Champions and troops. Each Champion is either a Fighter, Mage or Thief, with various abilities.
All units gain experience by defeating others in battle.
Higher level troops are far more effective. It is vital to build a cadre of seasoned troops and guard them from death at all costs. They serve as your backbone in any engagement. Fortunately, damaged units heal over time, either by resting, or for certain Faiths, through the spells of your mages. You can also pay crystals at a temple in one of your cities to heal troops, if you have the crystals of course.
