The Ninja is most likely to learn Scouting and Death Magic and fairly likely to learn the Combat and Chaos magic skills. Ninjas cannot learn Nobility, Life Magic or Nature Magic when leveling up unless some basic training in those skills is already known.
Attacking with a creature first, to help the ninja avoid retaliation, or just casting spells, are the best ways to use the ninja.
