How to make werewolves spar?

It's an interaction on the other werewolves, I think (I haven't used it yet, though I need to) under the Werewolf menu.

You might need to be friends, or at least acquaintances, first

The sparring grounds are a kinda torn up oval of ground over by the Portal Pottys

Thank you for the sparring grounds location. On my way.

Turns out they also need Transformation_Mastery

@Wndblwz you don't have to do it at the sparring grounds; anyplace outdoors with plenty of space around it will do.

Yup... Had a good ol' time sparring everyone last night. :)
