The way to learn new skills

Your aion character will have very few skills that can be used once you have entered the world of Atreia. As we all know that, your character will go through the journey smoothly and quickly, as your character can master these skills. Through your efforts on advancing to a higher leveling, to reach the appropriate levels you will be able to learn new skills. To find these skills you will need to find the trainer appropriate to your class in the nearby town. You also can purchase a book on this knowledge from this vendor that will teach you new skills. In order to check whether you have high enough level you can mouse-over the book to read its description, which includes the minimum level needed to learn that skill.
Books that are highlighted in red by the vendor are to high level for you to learn or are not available to your class. Moreover, the books tooltip will tell you if you already know that skill.
After you have purchased your skill books, all you need to do is to open your inventory and right-click o nthe book to add the skill to your skill list. Afterwards, a quick animation together with a ping sound will occur to indicate you that the spell has been learned and the skill book will be removed from your inventory.
