I've had a couple requests from my players for a "mentor" for the couple of force sensitive characters in the group. Rahm Kota came up a couple times as they've already joined up with the rebels. Just trying to peg down an idea of what to stat him without making him terribly OP (Jedi Master General and old veteran after all)

You could go with the profile for one of the mentors from Disciples of Harmony (The Trainer would be most suited in this case, I think).

Erm mm I don't know. When building jedi of a higher level I figure out about what suljo warde is at and apply additional stats atop. Especially if you're using a relevant character.

Don't give him stats. Keep him narrative only ... if he fights with the players, have him offscreen fighting other things, or keeping a big bad guy away from the PC's. Think Obi-wan in Ep IV. He really wasn't present for most fights, if the PC's are Luke, Han and Leia. He stops a fight in the cantina, splits off to disable the tractor beam on his own, then fights Vader, keeping him away from the PC's.

If you give him stats, you severely limit his use, and allow him to be killed.
