What are the requirements for........Spoiler

[Darth Xanax]

I've done this once before already but I was just curious if anyone knew
specifically what level yourself or atton have to be on so you can begin
training him to become a Jedi?

Can you train him if you are dark side or light side?

You have to go through a specific dialogue with him first?

[Obi-Wan-Evan]

The level doesn't matter but you need some influence with him.

You can train him either light side or dark.

And you have to have gone through Nar Shadda and paid the 2 t'wiliks 25 credits for some info regarding Atton.
