How to Get the Brimstone Gas Mask in Crimson Desert
Give Kliff Brimstone immunity that he needs via this unique headgear.

The Brimstone Gas Mask is one of the unique headgears in Crimson Desert that comes with a unique feature. But, to get it, you will need to leave Hernand and basically run north of Demeniss.
Brimstone Gas Mask Location

You can obtain the Brimstone Gas Mask outside a house located west of the Honeywood Apiary in Crimson Desert.
To reach this particular POI, Honeywood Apiary, open the map and go north from the “M” symbol of Demeniss. After that, go west, and you will stumble on a path that intersects, going north and west. Take the west road, and you will reach a house in Burnhand Quarry of Byron Estate.

Outside this house, spot the tree log near some logs and collect the Brimstone Gas Mask lying over it in Crimson Desert.

Regardless of your in-game progression, you can come here anytime and collect the Brimstone Mask in the game. Just make sure you have a horse to get from Hernand to Demeniss quickly. Otherwise, journeying on foot will take a lot of your time.
What to do with the Brimstone Gas Mask
The Brimstone Gas Mask comes with 100 durability, Brimstone status effect immunity, and 3 Defense. It is unclear at the moment if Kliff actually takes no damage from the red mist or gas while wearing this mask. I am still testing the use case of this headgear and the best situation to use it in the game.
