Another a info-quest, so don't expect XP. In this diversion, you'll take a trip to the pits to watch one of your recruited captains go toe-to-toe with another orc.
There's absolutely no way to influence the outcome, so just let the battle play out. If your guy survives, he'll level up, and you'll get the gear from his opponent. If your guy falls, you get his gear, and a new job opening.
Completing this quest opens up the last two regions in the game, as well as the Challenges mechanic.
