I have just taken this perk for the first time, mostly to neuter the nightstalkers. It's also nice to not have to shoot coyotes.

One unexpected bonus came when helping out Barton Thorne. When that rat followed me up the trail, the geckos got him and one ended up sitting on his back.

Anyway, has anyone found it useful to take the second level of this perk? About the only example I can think of would be if nightstalkers would help you out in OWB.
