I always find myself getting lost hunting in Red Dead Online.
Probably should be using my time more wisely but I think it's one of the most fulfilling features.
Especially when you suck at it like me.
Lets figure out how to hunt down the Legendary Nightwalker Panther and where is it!
Legendary Nightwalker Panther
The Legendary Nightwalker Panther can only be found when in free roam.
The highest chance of it spawning is between 5 pm and 5 am.
Best conditions would be foggy weather.
You can find the Panther in the locations marked in the yellow circle below.

You'll have to do a few things to complete the compendium in the animal field guide including:
You won't be able to take a sample and skin the animal in the same encounter.
Meaning you'll have to find the legendary animal twice to complete the compendium entry.
