Violatile firebottle is locked -- need help with one of the challenges

[XjaegerbombX]

So its the challenge after killing 8 consecutive small-game kills with a bow.

I crafted everything *except* the firebottle - Violatile and when I press Triangle to show all, the firebottle Violatile craft option is actually locked.

 

I have boughten every single pamphlet -- am I missing something? (Obviously I am)

 

Any help?

 

 

Edit: I managed to do a google search that shows I need to go a little north of horseshoe overlook to get the pamphlet. Just incase anyone needed to know.

To find the crafting recipe for Volatile Fire Bottles, look for the remnants of a Brush Fire just to the Northwest of Horseshoe Overlook, and in the middle of the burnt area there is a surviving chest that holds the recipe.

Also make sure to "read" the pamphlet. Simply owning it does not learn the recipe.
