So to make his living, he plans on using his sword talent (to which he trained his butt off) to pass the scholarship exam and become an adventurer (which worked very good, since he's the top of the class in terms of swords).

Sword Talent

 * Immense Prowess - Erwin has a great prowess with the sword, evidenced by the fact that he is the top swordsman in the Adventurer's School.

This is further evidenced that he can wield a magic katana while having normal human mana with ease, showing his diversity in his swordsmanship.
