NPC's not attacking Wolf-Formed players?
 

I'm not sure if this was intended to be as such, but I do recall finding foolish Druids running from a massive train of Fironia Vie NPC's (Pilgrims, Explorers?) after having used a Wolf Form type of illusion;

I tried various tiers of the Wolf Form on my Druid and did not strike up a stir in FV; Kinda miss seeing dead Wolf corpses lingering around the city of FV..

For some reason there are 3 different factions for FV, will work on it but it will take some time.

Fixed, pending update.

Wolf form should also cause you to be kos to NPCs in Everfrost, is that accurate here?

As of last patch, yes.

Feel free to PM me any other groups of city NPCs that you remember KOSing wolf form.
