If Shepard assists Ratch with killing some vermin, free Pyjak Meat becomes available from Ratch's Wares and can be fed to Urz. After devouring the meat, Urz will start following Shepard around the camp and may be entered into the varren pit fight. Urz was a former champion pit fighter, and as such he has a high probability of winning and a corresponding higher bet: 500 credits instead of 250.
Should Urz lose a fight, he will relocate to the nearby med-lab and become temporarily unavailable for pit combat. Shepard's squadmates may comment on the varren's condition when prompted. If Shepard leaves the camp and the injured Urz behind, the varren will be be up and running again by the time the Commander gets back.
- When betting against Urz and winning repeatedly, after about 10 times the payout will be a sole credit. Completing an assignment or mission resets this. (PC version 1.01, PS3).
