Bog Lurker
Bog Lurker is a rare elemental that can be found in Zangarmarsh. He is most commonly seen wondering around the Corrupt Draenor villages of Zangarmarsh. He can spawn near any of the 3 main villages but he is most commonly found around the one in center Zangarmarsh. If you're looking for a place to farm while you wait for him, the one in center Zangarmarsh is the best.
Every 10-15 minutes mount up and fly around the 3 locations he can spawn and spam a macro with /target Bog Lurker .
