Here is my post. I took some of the code from someone else for the horde vendor. The hotspots are for the obsidian mobs in the obsidian forest and for the gryphons and owls south of kirthaven. Does pretty good at raking in dragon flank. Not so much with the delicate wing.
Use at your own risk. I've never had it vendor or repair cause I just use it will I am at the PC.
