Hello.

For Hans Client Quest - Clapperclaws on a violent forest - I complete it by just doing the forest boss at the end. But on the quest it says to kill Fang Banshee and a Fang Banser for some reason.

See Below:

@lxRIVExl They are two separate enemies, just like Snow Banser and Snow Banshee. Banser is typically just a random spawn in Forest and Ruins, but it can also be paired with Banshee as the end boss in Forest AQ, and you can also find a guaranteed one on one of the paths in Running Maneuvers: Naverius I.
