Other good option to start the Demons task I'd recommend you to go to Demons at the restricted area at Yalahar, Yalahar (Magician Quarter), there you will need to spend a Energy Soil (energy, earth...) to acess the area. You have two options to go in, I recommend the respawn on respawns, each one with at leasr 5 demons and a good space to run without lure more than one Demon per time. You might start hunting at the left side.respawn. Also you should search videos at youtube, there are lots of them explaning how to hunt at this área. place.
