Death & Nobility
The Dark Lord is most likely to learn Nobility and Death Magic and fairly likely to learn the Tactics, Combat and Chaos magic skills. Dark Lords can not learn Life Magic or Nature Magic when leveling up unless some basic training in those skills is already known.
While the Sorrow spell can be annoying for the opponent, it only costs three mana, and casting it won't leave the hero open for retaliation. This ability is usually only useful if the hero also has several levels in the Combat skill.
