Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks Locked Chest in Sinister Cavern??

In Sinister Cavern where you find Barnabus there is a cave that ends with a lava machine. On the right before you reach the end of the cave there is a chest that needs a key. I have searched everywhere in that cave over and over but can't find the key to open it. I will take a pic if needed..... If anyone knows where this key is located it would be much appreciated if you could let me know.

here is the pic of the location of the chest :

Nobody remembers where this key is located?

I remember finding the key but don't remember where. It was in a different area. I don't remember that there was anything worthwhile in the chest, though.

Ok thanks for your response. I am just a loot monger and get ticked when I can't open a chest.:-)why they made some keys so easy and some so hard to find I don't know.
