* There is a 40% chance that Victanir will spawn in the center of the Yellow Sands zone of the Nam-Yensa Sandsea when you enter. Just leave and re-enter if it does not appear. Note though that Victanir is partially invisible and can be difficult to see. You also need to have initiated the Hunt Club side quest.
