There are several of each is why I think there is some confusion. I know of at least two pirate fire brand spots on the far south cave. Also besides the one that walks by the chained king the one that walks from the far wall to back near the bridge/castle is also a battle skewer mob. I'm sure there are at least 2 maybe 3 hawkhurst mobs that drop the torch also. I'll try to go look at some ss to remember which one ( think its near the bridge ).
It's just the spawn rates are so low it's hard to find the locations now.
I think you are right. I didnt know there were so many spots when i started making this guide. I'll be adding in these other locations, and trying to find more now i know there are so many. To everyone that posted and PM'ed me, thanks for the info!
