The creatures that spawn randomly in the wild are the Riftspawn and Morthalspawn.
Each spider will have 1 Frostbite venom, while the Giant Frostbite Spiders can have up to 2.
Cronvangr Cave
Cronvangr Cave is a large, dark cave located east of Mixwater Mill, south-southwest of the city of Windhelm. It is a popular spot for adventurers because it is home to a large and dangerous dragon.
If you’re looking for a unique experience, you can follow the river south to find a dead mammoth caught in a web. A few spider egg sacks can also be found at the entrance. ..
In the first room, there will be six Frostbite Spiders. They will swarm you, but don’t worry. These spiders are relatively easy to kill.
To the left of the small tunnel is a path leading down into a puddle of water at the bottom of the cavern. There are Frostbite Spiders along this path.
The path to the east leads you down a deep, dark tunnel.
This leads to another area called Cronvangr Broodlair, where a Giant Frostbite Spider is waiting for you (along with several small ones).
Redbelly Mine
The Redbelly Mine can be found in the town of Shor’s Stone, north of Riften. It is a small, dark hole in the ground that is home to a number of dangerous creatures. The Redbelly Mine is a great place to find gold and other valuable items.
The quest “Mine or Yours” can be obtained from the town blacksmith Filnjar before entering the Redbelly Mine. In this quest, you need to clear Redbelly Mine from Frostbite Spiders.
In this mine, there are several Frostbite Spiders that will attack you. So take them out and loot for Frostbite Venom. Then follow the wooden path to the left and into the bottom of the mine, where another group of spiders can be found.
