I've been having a lot of fun with a Celestial/Grieving build. Both for 1v1's and small scale it's quite effective!
I've been feeling like I want to take Staff for the utility and the benefits it provides for kiting but I can't decide which weapon set is worth trading it for. If I swap out Axe I lose most of my power damage and if I swap out Scepter I lose most of my condition damage.
Anyway, I don't think this is a new idea. Pretty sure Cele core Necro has been used and discussed before but I wanted to share. If you're looking for an effective core build, this one is quite strong. A little adjusting with the weapons and utilities may help to better suit your needs. This is just how I prefer to play it as of right now.
