Mamut's Bones Aion Quest

I've had some trouble when I reached this quest because I couldn't find the mamut bones so I decided that I have to post this, in case others are looking too. It's not a hard quest, but it takes some time if you don't know where the items you need are located. Anyway, I hope it will help you guys.
