How do you be assasin in Final Fantasy Tactis advanced?

Answer 1

Vieras are the only race that can access the Assassin class. For a Viera to become an Assassin, she must have mastered 1 Sniper and 2 Elementalist A-abilities. To become a Sniper, she must master 2 Archer A-abilities, and to become an Elementalist, she must master 1 Fencer and 1 White Mage A-ability. By A-ability, I mean an ability that you have to actively choose from the battle menu, so not a reaction, support, or combo ability. Hope this helps!
