[eppy19]

I am only at about level 20 i am in the Viera Village I was womdering do you guys think it's possible to get any "optional" espers with my level or should i wait? Oh yeah also where can I buy Thundara, Fira, and Blizzara?

You can buy the 'ra' after in Eruyt Village after Henne Mines.

You should be at least level 25 when you reach Eruyt Village if you want to survive next dungeon, go and train more in the jungle. Do you train your reserve?

The lowest level you'll want to try fighting an optional Esper is 30 but higher level is recommended.
