Two of the bestskills are Resurrect and Aura of Command. With these two skills, you can have some of the best creatures fight for you. Kill a Boss-like creature, then resurrect him. After that, cast Aura Of Command on him. He will join your team and protect you. Try this on the dead Dragonrider south of Aleroth and the Protector of the Cyclops Eye (he conjures conjurers). Anything that leaves a carcass can aid your fight.
