Specialization

Specialization (特質系, Tokushitsukei) is one of the six categories of Nen aura types.

Description
If a student causes some other effect during their water divination, they are Specialist (特質系, Tokushitsukei). It is possible that the effect that occurs can give some insight into how they should direct their ability. Specialization is anything that doesn't belong into the other five categories. This is the vaguest Hatsu category. For example, Kurapika's Specialist ability allows him to use all Hatsu types at 100% efficiency. Chrollo Lucilfer's Specialist ability allows him to steal any other Nen ability (provided that the right conditions have been fulfilled). Neon Nostrade's specialization ability is unique, as it seems she uses only the abilities of Conjurer and Manipulator out of any of the other five Hatsu types. It is possible to become a Specialist later in life, although it is more likely for Manipulators or Conjurers which is why it is placed at the bottom of the chart.
