My players are in a DarkSun Gladiator adventure. They are stripped of all items, they are slaves and own nothing. In a major battle I need a CR 5-10 monster (low INT, warm climate), that can be controlled by a lure of a sort. Some odor, smell, or something?... Im hoping that the PC's can lure it to to attack the high priest at the box seating. Any suggestions?
Off the top of my head I know that grey renders will sometimes 'adopt' weaker creatures. Perhaps one could take a liking to your players and help them out in exchange for food.
