Skill Trainers sell many skillbooks players to learn higher level skills. There are also a few that are quest rewards, or drops. From Level 10 to Level 40 you get new books every three levels, and after 40 there are new skills each level. Beginning skill trainers are found in Aldelle Village in Ishalgen and Akarios Village in Poeta. As you progress, quests will link you to the next skill trainer that you need to access. After level 10, skill trainers in Pandaemonium are in the Great Temple, the Capitol Building and Marchutan Priory. In Sanctum, the trainers are in the Lyceum, Protectors Hall and the Cloister of Kaisinel.
