A Sunspear skill is any skill tied to a character's progress in the Sunspear title track. There are currently 11 Sunspear skills: one general skill, and one skill specific for each profession. Sunspear skills are PvE skills, and thus differ from regular skills in many ways. First, they cannot be used in PvP; all Sunspear skills are marked as PvE-only. This means that they cannot be unlocked on your account and thus cannot be learned with Skill Tomes. Secondly, they cannot be used by heroes. Finally, they are generally more powerful than standard skills.
