I need to hunt a named Greater Nix beetle called Frostbite for one of my Dragon quests. He's supposed to be located in the Mahagra tundra around the co-ordinates 252,304 but I just spent 2 hours looking around there for him and I found plenty of Nix beetles but no sign of this particular beetle. Is his spawn point shared with the other beetles,or is there a special location that I'm not looking in for it?
