Graverobber hits very hard, and it's aoe which means you can't dodge it. If you see a harmony necro (aka a necro using graverobber) be prepared for a stun into graverobber. The stuns will likely be either Dark Convergence or Dawnbreaker, both of which are very easily blocked if you're ready for them. If you block the stun, block the graverobber as well.
Its something you just kind of have to be ready for if there's a harmony necro around. Another easy way of dealing with it is by building movement speed into your build; a necro will have a much harder time landing graverobber on you if they can't keep up with you.
