Development Abilities (発展アビリティ) are special abilities that have a chance of appearing every level up starting from Level 2.


Development abilities are different from basic abilities in the sense that they are characteristics specializing in a certain area. Starting from Level 2, there is a chance of gaining one every rank up. There is also the chance of one not appearing at rank up, or multiple appearing to choose from. Bell's Luck, Ais' Swordsman, Abnormal Resistance, and Hunter are examples of choosing from multiple development abilities. Like basic abilities, development abilities are also categorized from I to S; however, they are much harder to train and do not reset to I at each new rank up. Additionally, development abilities can improve during a normal status update.
