You can go to any zone with this yeti that players are allowed into at the moment. Yeti controls are simple, right click on the target you want to kill (you will hear the yeti roar before attacking if you did this right). The first hotkey to jump to another selected area within 30-60 yards. The second hotkey for when you encounter an enemy yeti and need to deal extra damage. The rest of the hotkeys are irrelevant.
