Khego
Less frequent but harder to flee from (and possibly also more rewarding?)
It's super annoying to have to flee from the train of King Kilrogs and Wyrms just to get across the screen. There's also zero chance of danger, unless you misclick maybe?
However, the ADD ambushes are kind of fun. The large groups of Wyrms and Knights can yield good XP.
Feel like this could be expanded on for other zones (level appropriate) to make them more interesting.
