About the hidden classes

[Vezzath]

If I complete the Appraiser quest with a character, is this npc available to everyone on the team, or only to the one who completed it? That is, if I create another archer, will I need to redo the quest with him, too? In case I am doing with my Swordman, when complete, npc will be available to my Archer?

Thank you in advance.

Thank you, it saves me a lot of time.
