Volatile Fire Farming
This guide will list the places where I found the most [Volatile Fire]. One thing I noticed while farming Volatile Fire is that sometimes you farm for 15 minutes and you don't get a single Volatile, this is just bad luck, don't get discouraged.
So, where to farm Volatile Fire?
Twilight Highlands is the best place to farm Volatile Fire. Kill Enslaved Infernos and combine it with fishing in Pool of Fire.
If your fishing skill is only 1, you can still fish in Pool of Fire. Each Pool of Fire contains 2-4 catches, each of which will be 1 or 2 Volatile Fire. The location have 4 pool spawning points. No more than 2 pools will be visible at one time, and none may be visible if pools have recently been fished empty. Pools respawn approximately 12-15 minutes. You can find the Pools around Lord Canon.
This is how the Pool of Fire looks like. The Pools are farmed by a lot of players but if you can do this alone, you will get 100+ Volatile Fire in an hour.
Flame Ascendants in Mount Hyjal have low HP and they respawn instantly most of the time. I was often able to kill 5-6 at the same spawning point, because the mob respawned before I even looted it.
There is also another Pool of Fire location in Mount Hyjal. This is a good place for lower levels to farm Volatile Fire because there are no mobs at this area.
Unbound Emberfiends in Twilight Highlands is another good alternative, these are a lot harder to kill than the mobs in Mount Hyjal.
