With the end of the Oriental Adventures campaign, I once again find myself behind the DM screen. After picking up a copy of Red Hand of Doom, I decided that it would fit nicely into the group's collectively built campaign world (before we went to Rokugan for a bit). However, the important villains throughout the adventure are too weak for the group of well-practiced optimizers I play with, so I decided to replace them all with custom villains of my own. However, I won't worry about the other villains until the group gets there.
So without further adieu, would this guy present a tough but fair challenge to my group, and if not, what could be done to fix it?
