Jack 
Many players search for “Fetid Key OSRS” when they want to understand a special key that unlocks bonus rewards. In the game, the correct item name is Brimstone Key. This key allows you to open the Brimstone chest, which gives random loot as a reward for completing Slayer tasks.

What Is the Fetid Key OSRS (Brimstone Key)?
The Fetid Key OSRS Brimstone Key is a reward item that drops while completing Slayer tasks assigned by Konar quo Maten. You cannot receive this key from other Slayer masters. It is exclusive to Konar’s tasks.
When you kill monsters assigned by Konar in the specific location she gives, those monsters have a chance to drop a Brimstone Key. Each key can only be used once. After opening the chest, the key disappears from your inventory.
This system encourages players to choose Konar for Slayer training.
How to Get a Brimstone Key in OSRS
To obtain a Brimstone Key, you must first receive a Slayer task from Konar quo Maten. She assigns monsters in specific locations across Gielinor. You must kill the exact monster in the exact location she assigns.
While killing these monsters, you have a chance to receive a Brimstone Key as a drop. The drop rate depends on the combat level of the monster you are fighting. Higher-level monsters generally offer better chances than lower-level ones.
You must remain on the active task. If you switch tasks or complete it, monsters will stop dropping the key.
Consistency is important. The more monsters you kill on Konar tasks, the more chances you create to receive keys.

Where to Use the Brimstone Key
You use the Brimstone Key on Mount Karuulm, near Konar’s location. The Brimstone Chest is placed close to where she stands.

There is no additional requirement to open the chest once you have the key.
Brimstone Chest Rewards Explained
The Brimstone Chest provides a variety of useful rewards. The loot is random, but it usually includes items that support Slayer training and account progression.
Common rewards include coins, rune equipment, ores, bars, herbs, and seeds. Some rewards are more valuable than others, but overall the chest offers balanced and steady profit over time.
For regular accounts, this means extra gold while training Slayer. For Ironman accounts, these supplies can significantly help with crafting, Herblore, and other skills.
Because rewards are random, opening the chest feels similar to opening a treasure box. Each key gives you a new chance at valuable loot.
Is the Brimstone Key Worth It?
Yes, for most players the Brimstone Key is worth collecting and using. You do not need to complete extra activities to get it. It drops naturally while training Slayer with Konar.
This makes it a passive bonus reward system. You train combat, earn Slayer experience, and receive additional loot at the same time.
If you focus heavily on efficiency and profit, Konar tasks combined with Brimstone Keys can be a smart long-term strategy.
