I updated the post with the ravager, hook wasp and fire/shadow wolf images, now that the patch is finally available.
One interesting thing to note. This is actually a later patch than the one where MMO-C first publicized the fire and shadow wolves, and they've
changed. The fire skin is now WAY less saturated. It would almost look acceptable on a regular wolf except that the contrast is still very high. Presumably they intend for their appearance to be controlled mostly by model effects, but I'm not yet seeing any special effects on the models. I guess we wait and see
Here's how they look currently (click to see larger images):
The fire version of the Frostwolf Pup has also changed dramatically but in this case it's now a wine colour, which seems odd. I know I'm not confusing it with the shadow skin as that's also present and is a darker and bluer colour. Here's how they look now (the first is fire):
Their models are likely also meant to have fire / shadow effects, which haven't been added yet.
