Duke's path forward has become clearer; with five Elemental Talents, following the path of the Elemental Mage is surely the most suitable.
Generally, once one becomes an Official Wizard of Level 1, they gradually define their future path and delve deeper into a specific direction.
For example, the Mechanical Wizard commonly seen on the East Coast, the Bloodline Mage inherited from the ancient era of sorcery, and the Astrologer that Duke once encountered.
It is worth mentioning that Duke learned from talking to Bell of the Knight Hall that knights also have a method of advancing by leveraging powerful bloodlines to enhance their Life Level.
In this aspect, knights and Bloodline Mages are very similar, essentially enhancing their Life Level through the fusion of powerful bloodlines.
Duke also thought about how the Elementalization of the Life Seed uses Elemental Power to complete the life-level ascension.
