Seriously, there are caves all over the place. Let them beat on you for a bit on the road or something then run to a nearby cave. Have a snare placed there ahead of time or rely on cavernfall or both.

I'm great at doing this part, unfortunately I suck so bad otherwise my baiting rarely managed to wipe anyone out.

Your right, not a lot of areas that are wholly caves and good places to hunt people, but that's a good thing. Caverndweller would be OP if they were everywhere.

Explorere/Caverndweller bonus: You can deafening howl/smoke screen anywhere that is indoor and wilderness. Doesn't have to be a cave. Never got to try cavernfall there, but if that works probably a bug.
