D&D has always been a game focused on a group of heroes striving to achieve similar goals (the important idea here being a "group"). Single combat is rare, if not outright discouraged. But if you're looking for a fun change of pace, consider the "Caravan of Glauu the Seer."
Glauu the ushemoi sorcerer travels the land with his school of top-notch gladiators. Arkamoi, hadrimoi, lashemoi -- he features them all, and is ready for any adventurers willing to put their lives on the line to please the crowd. In a series of one-on-one battles, each hero who enters the arena can earn eternal glory . . . at the risk of a quick trip to the afterlife. Do your PCs have what it takes to compete in Glauu's bloody ring?
