Completing the Search: Finding the Castle Grounds Hut Key in Atomfall

Select Language:

The druids residing in Casterfell Woods utilize an ancient castle as their headquarters in Atomfall. While sneaking into a lair of a ruthless cult may not sound very wise, certain game objectives will encourage you to do just that.

As you navigate the castle grounds, you might stumble upon a locked hut that requires a specific key to access. Unlike many of the other keys scattered throughout the game, this one isn’t within the castle itself—you’ll need to trek into the dense woods to find it.

How to Locate the Castle Grounds Hut Key

You can find the key inside a small cave located quite far from the castle on the opposite side of Casterfell Woods. Specifically, it’s at coordinates 24.7E, 85.6N, just behind Datlow Hall. Be aware that this cave is filled with harmful spores and a hostile plant that spits venom, so prepare accordingly before venturing in.

Before Heading to the Cave

It’s advisable to first explore the castle and obtain the recipe for Strange Tonic and Mother Jago’s Book from the kitchen. Consuming the Tonic will help you resist the infection caused by the cave’s spores, so be sure to mix it up and drink it before you enter.

You have the option to trade for a Strange Tonic directly from Mother Jago, although her supply may be limited.

How to Retrieve the Key

The simplest approach to find the key is to enter Datlow Hall through the front entrance and make your way around the back in a clockwise direction. Be cautious of the many tripwires in the garden; once you reach the back, slip between the shed and the car to emerge behind the estate.

Continue straight ahead, where you’ll encounter the infection spores and a deceased scientist to your right. Ensure you are fully healed and drink the Strange Tonic at this point.

The body has a note referencing Mother Jago along with some crafting supplies, but nothing too significant.

Steer clear of the spitting plant located in the center of the spores, and as soon as you enter the infection zone, take an immediate right to find the cave entrance. Beware of exploding spore clusters that can damage you, no matter how prepared you are.

Even if you’re less likely to get infected, being in the infection cloud still causes damage over time. Don’t stick around!

Inside the cave, look for another corpse and take the key from it before promptly vacating the area for safety.

Finding the Castle Grounds Hut

When facing the main doors of the castle, the hut is directly to the left. Its coordinates are 19.9E, 83.6N.

Inside, you’ll find a BARD Crate as the main reward, which contains a Training Stimulant to help you learn new skills. You’ll also discover Iodine, a rare crafting material for medicine, along with some ammo and bandages, both of which are extremely valuable in a survival scenario like this.
