Doom Scythe

Do you remember those cheap, flying croissants that were so prevalent in early 6th Ed. tournaments? Well, here's their older brother.

On the Tabletop

5th Edition

It's basically a Night Scythe with the portal-gun replaced by a S10 AP1 Death Ray, it has random range (in this case the average being 22.5" range), its able to aim anywhere, allowing you to shoot at two different units or place it where a unit is outside cover. While S10 AP1 makes it look made to go for vehicles Necrons are able to anti-tank like no other, so the Death Ray is instead useful at wounding high toughness and/or low armour save (2+) models, which Necrons have trouble fighting (looking at you, Wraithknight), instagibbing multi-wound infantry (Centurions, Obliterators, Nobs, Ogryns) or occasional T5 MC (Daemon Prince), plus it laughs at Imperial Knights and their ion save, as well as Flyers in Hover Mode and Gliding FMCs.

Its only real weakness is small base models since it can be a pain to line up more than 5. Than again, even five S10 AP2 auto hits are close to the volley of bolter fire in effectiveness against your average Ork Boyz mob, or Fire Warrior squad, and while it loses dffeiciency against sprreaded low-armour save targets, twin-liked tesla destruktor rises it's own. With a larger base unit like Terminators, Wraithguard or Warriors, the Death Ray can easily hit the whole unit if you place the Doom Scythe the right way.
