Evantil, The Vile Oak - Burntbark Camp
The only thing that Burntbark drops of value is his aug. It's called Fear Infused Charcoal and it is a pretty good aug for higher level tanks or healers and melee because of the armor class and Heroic Agility that it offers.
Aside from this aug there isn't anything else of value from this camp. Also, this camp isn't that good for grinding out experience either since the mobs are so spaced out in this part of the zone. What I usually do, instead of actually sitting down and camping here, is I clear the treants out of this area while doing other things like Tasks or something like that. Since this camp is really good for nothing but Burntbark it will be the only way to make coming to this area worth it.
As far as everything else in the area, all of the mobs are extremely easy to kill and Burntbark is really nothing more than a simple tank and spank type of fight. Below is a picture of the two known places Burntbark spawns and the locations I recommend you camp for him if you decide to wait for him to spawn. Both little blue circles will work fine for camp locations, I usually alter between the two depending on where it is Burntbark spawns. Though, I honestly have never seen him spawn anywhere but the northern most (#1) on my map below.
If you don't feel like just sitting around waiting for Burntbark to spawn after you clear the few placeholders in the area I strongly recommend you run around and gather up the collectibles while you wait. There are quite a few that you can find all across this zone and in the pits surrounding the Burntbark area, you could make a decent amount of plat while you're just waiting on Burntbark.
