In Pathfinder, they ARE Oni and there are a few different types. While you may not be using Pathfinder specifically, just shows that someone at least made that specific connection. Don't really have too much to add really. Looking through some older 'oriental adventures/bestiaries' would definitely be a good idea. Gnolls themselves, while neat, are generally kind of boring. Some ninja gnolls could be pretty badass though.Well, the Ogre Mage I chose because they are regularly depicted as Oni, and Gnolls as they fit hengeyokai theme. So we were thinking along the same line![]()
