Is the best place to level your Chocobo companion still at the one spot where all the water sprites and Odin spawn? I am almost done with the MQ and I am looking into levelin my companion, but not sure where to go since there is scarce the info on the topic.

Also, has anyone reached level 20 yet on theirs? or did that not get implemented in the game yet?

Why is it so hard to find info on all this stuff about chocobos?
