How can you fight Elvarg in Dragon Slayer again?

;-) you cant do the quest again once done the quest there's no redoing. Unless your a member and go to where the hill giants are located on non member worlds. But in member worlds there's no hill giants. There is dragons. This is located in the wilderness near clan wars. The dragons are the equivalent strength as Elvarg. They also vary in colours as there are many of them. It's a really popular because it's really easy and fast way to earn money from their bones which may cost around 5k each!
