Super Rare dens offer you the best quality eggs in Monster Hunter Stories 3, and finding a bunch of these will be immensely helpful to find monsties with superior genes.
It doesn’t require a degree in Rocket Science to understand why Super Rare den spawns are so important. However, these dens are extremely rare (as their names suggest). Thankfully, a few tips and tricks can almost guarantee a Super Rare den spawn.
How to find Super Rare dens easily in Monster Hunter Stories 3
Super Rare dens are highlighted by their blue colour, and they provide you with the best eggs you can find. However, these dens don’t spawn commonly, and you’ll come across occasions when you won’t find a single one on the map. However, there’s an easy way to bypass this problem.

Den spawns are reset whenever you load an area. This applies to broader areas like Azuria, Canalta Timberland, etc., and also to minor areas like Blightstone Woods, Ashen Pass, and more. When you load the save for the first time, it will reload a place. However, repeating this process takes a long time, and it’s not something I will suggest.

An easier way to save time and reload the map is to be at points where an area ends and another begins. If you refer to the image above, you’ll find that I am at the point where you enter Ashen Pass from Blightstone Woods.
What you have to do is switch between the two areas until you find a Super Rare den spawn. Enter a new area, and open the map. If you find a Super Rare den, find it to get higher-quality eggs. If not, just go back to the previous area. Wait a few seconds for the new map to load, and look for the Super Rare den. You can repeat the process until you have found one.
While the process might be tiring, it does guarantee you at least one Super Rare den spawn at all times. Always remember to change the time to night since Super Rare dens don’t spawn during the day.
