This only took me about 10-15 minutes.
I initially tried the method of running around the entry to Fortuna but i had no luck so i just ran around the snowy areas on foot. So equip a weapon that has a bit of crowd control, for example, i used my ignis. Also unequip any sentinels and just run around in the snowy areas. When you see a group of raknoids, simply double jump and hold left trigger to aim glide then shoot them. Equipping a mod that shows enemy locations on your minimap might also help but not necessary.
