Studying Dragon Arts allows you to receive a variety of bonuses, such as an increased Resource production rate, accelerated Unit Training and Movement Speed, Offense and Defense Boosts, and much more. In order to discover and upgrade Dragon Arts, you will require Dragon Points.
Moreover, you will need Dragon Marks and Dragon Points to discover the Dragon Art "3rd Additional Slot", and Sapphires to discover the special Dragon Arts that unlock the 4th and 5th Additional Slots. These will allow you to choose an increased number of Dragon Arts to receive Bonuses from.
Dragon Arts are divided into two major groups - Conventional and Arcane Dragon Arts. The main difference between the two is as follows: the Bonuses from Conventional Dragon Arts can be activated without Dragon Marks, while Arcane Dragon Art Bonuses require Dragon Marks to activate.
Dragon Arts are also classified as: Elementary Dragon Arts, Advanced Dragon Arts and Elite Dragon Arts. Elementary Dragon Arts can be found near the top of the Dragon Arts Tree, while Advanced and Elite Dragon Arts are found further down.
Each Elementary Dragon Art has a corresponding Advanced Dragon Art, which is distinguished by a round icon with the numeral II. Advanced Dragon Arts become available as soon as you have upgraded the corresponding Elementary Dragon Art to the maximum Level available. Elite Dragon Arts are marked by the numeral III. Each of them will become available as soon as you have upgraded their corresponding Advanced Dragon Art to the maximum Level.
