Guide awaiting review
Reach Level 60 First
The treasure and its cauldron will not appear until you are level 60. If you arrive and only see the two NPCs without the cauldron, you must reach level 60 before it becomes visible.
Locate the Cauldron
Once you are level 60, return to the treasure location in Revendreth where the two NPCs are found and the cauldron will now be present and interactable.
Use the Cauldron
Interact with the cauldron and use the infused rubies on it to receive the Muckpool Cookpot toy.
Tips
The Muckpool Cookpot has a 5-minute cooldown and also lasts for 5 minutes, making it a full campfire replacement for both cooking and roleplay purposes.
Cooking fire toys including the Muckpool Cookpot share a cooldown with similar toys such as
Little Wickerman, 
Grim Campfire, 
Cozy Bonfire, 
Steamworks Sausage Grill, 
Eternal Kiln, and 
Crystalline Campfire, meaning only one can be active at a time.
