Under e. Republic Side Summary it list the trooper for treasure hunting.As you noticed yourself non of the Trooper companions have any bonus at all for treasure hunting.
Thought you mixed it up with Aric Jorgan +2 crit diplomacy. Which I suggest you should add to the side summary.
I think you're right, thanks for pointing that out. I'm gonna go check now.
I can't imagine why I made this error. Either way it let me edit that the Jedi Consular was by far better. I think I meant to say that the smuggler was +2 crit, but that wasn't the best either. Either way I appreciate that you pointed this out, thanks!
