The best item i found was a (?) Keeper Robe. I can't remember the first word but it's called blank(?) keeper Robe, I found it in the Queens palace in the Jedi artifact room. It looks the same as all robes and has a reddish brown color, it does'nt look good but it's the best(stat wise) Robe I could find in the game. I was dissapointed I did'nt find any unique(like the star forge robes from the first game) robes in the game.
EDIT: It's the Ossus Keeper Robe, and it's ugly.
