My group recently started a a new campaign together and so far everything is going fine, the group is awesome and the GM has not killed us all...yet.
The main problem is our skill monkey rogue.
So it has finally been revealed to me that the rogue is stealing my items, wondrous items, and gold regularly and has sold it for for gp.
My first reaction was to confront the rogue in game and stop him. He supposedly does and then later keeps stealing my gear.
Normally i went to the GM to get it sorted out after the session and he doesn't care and tells me to deal with it myself.
I later asked if i could just force the rogue player to reroll by either kicking his rogue out of the group or killing him,
both of which i could do extremely well. The GM, after running the idea by him, says that i can't. I asked if i could pin and tie him up and just carry him everywhere, still the GM says no.
So after looking around on wondrous items and forums i can't think of anything to stop the rogue reliably or make everyone else want to kill him.
So here i am asking this question, how do you defeat a skill monkey rogue without killing him?
Notes about situation to help-
-the rogue in question gets a +26 to all sleight of hand roles and normally takes 10 when stealing from me.
-i am a grabble based brawler and he has no ranks in escape artist
-i have 14300gp and we are in a metropolis so i can buy anything i want including wondrous items
