Class and Job symbols: question.

[Kamifubuki-Yoakesetsuri]

Arcanist is an aetherometer if I remember correctly. They appear in the Monk job quest when a ACN asks you to take aether readings in various areas.

Thaumaturge looks to be flames, or even flames being emitted from the head of a staff.

Summoner looks to be a geometric symbol. Makes sense due to geometry playing a huge roll in their magicks.

Scholar is a pair of glasses, which makes one look scholarly.

Scholar sign is a book not glasses.
