It came from the invasion.thx @MalagAste, i remember that the invasion with Pyros had the plate set, with also general etc... not this bear mask
i search for it on atlantic and on other shard, no way.
someone else have info?
It's level 3.You can currently get this bear mask doing the khaldin champion spawn at level 2. They also have other cool hues like the captains cloaks at level 3 or 4. [I forgot which].
