On Ragnarok they are mostly found in the highlands (the green patch on the NE of the map) But they can also ne found behind the murder snow area (closer to the West of the map but still in the middle) just found a lvl 130 today and I MIGHT tame it in the future. On the Island look on the mountain in the center of the map or od you are feelings extra ballsy you can look in the 2 mountains in the snow area. Stay safe and good luck. Survivor out.
