Unlike other demon hunters she uses a scythe instead of warglaive. Not sure if this is a bug or she's an unorthodox demon hunter or if bliz has the intention to give demon hunters the ability to use polearms.

She's using something called the Scythe of Souls according to the Mardum quests - some kind of artifact that's part of the Mardum plot in some capacity.
Details
This roster comes from the current game client's data files, so it is not a complete list of every NPC in the game - older world NPCs that are no longer in the modern client are absent.

I hope that they give DHs polearm proficiency, post-Legion- considering that Hunters and Druids are agi-polearm users. I understand that Warglaive weapons as a "DH only" thing may be great for some people's class "fantasy" (as is Legion's design narrative)- but, ultimately, I'd also like to see Warriors, Paladins (and possibly Hunters) get the glaives too. See [npc=16222] and Warcraft "Shadow Hunter" troll units.
