You're are not missing much anyway. So, don't beat yourself up looking for it. Yeah, it's a diversion when you make the staff but, it's not like OMG this is insanely fun! You have to break up the monotony. Do some rifts. Farm for gemstone. Do some bounties. Farm for gemstone. I went not stop farming for it and it was not fun. I started doing it here and there and got it eventually without as much boredom and frustration.
