Easy experience
On the missions where you receive bonus experience for something (appears in green writing in the upper left corner), exit back to the world map and replay the level to keep the bonus experience. This is a good way to level up your characters early.

Defeating Earth Golems
An easy way to kill Earth Golems is with cavalry. Make a waypoint on the Golem, then one away, and another one. Keep repeating this until the Earth Golem falls. It is that this be done with Orc Riders because you can use Enrage to heal them. This is very helpful in Urrukabar's first mission, as there will be about five to seven Earth Golems.
