The Warlock is most likely to learn Chaos magic and Nature magic and fairly likely to learn the Death magic skill. Warlocks cannot learn Order magic when leveling up unless some basic training in those skills is already known.
A poor advanced class, the warlock gets a bonus weaker than most secondary skills. Any level in a spell point skill (like Herbalism or Conjuration) would provide the same bonus. The combination of creature-summoning Nature magic and damaging Chaos magic is still powerful, however.
