Raw Hide! Hearth Magic should be considered assault.

At 300 XP cost to stun a horse, I believe that there should be consequences for the players actions. Therefore it should leave an assault scent and require the proper skills for assault.

The problem with doing that is hermits who are trying to get away would no longer be able to get away from horse raiders unless they invested into red skills.

There'd also be the fun possible situation of getting chased by people on horses and raw hiding someone among them who has not (yet) initiated combat with you.
