Necron rules seem to be keeping pace with Space Marines- so check out all the codex reveals and datasheet rules we’ve seen so far.
Different sources all over the web have been posting up pictures of datasheets. Compiling everything together for the Necrons, here’s a consolidated list of updated datasheets on the way to Necrons once their big October codex release rolls around. There have been some nerfs here and there, but overall, it looks like Necrons are making out even better than before.
As a quick reference, we’ve got all the datasheets listed here.
- Immortals
- Deathmarks
- Triarch Stalker
- Wraiths
- Ghost Ark/Doomsday Ark
- Night Scythe/Doom Scythe
- Tomb Blades
- Technomancer
- Annihilation Barge
- Overlord
- Catacomb Command Barge
Necron Dynasties 9th Edition 40k Rules
u/Drallcom3 on Reddit, posted a link that leads to a picture of a blurry Necron dynasty rules sheet. WARNING, when we clicked on the link, we instantly got about three malware blockage notices so we wouldn’t recommend going there yourself. Luckily, somebody transcribed it all and we managed to take a quick pic of the rules before we got off the page.

What Are These Protocols?
You probably noticed at the bottom of each of these dynasty rules lists are these things called “protocols”. There seems to be a split in the community of what these are exactly.

However, once a certain stage of the Necron’s protocol activates, the Stratagem becomes super useful as you get both effects. It’s total speculation right now but it’s worth a mention as the Space Marines seem to be getting trait updates as well.

Ghost Ark/Doomsday Ark Updates

Night Scythe/ Doom Scythe Updates
- Its maximum movement range decreased by 10″ across the board from 50/40/30. This makes sense because of the smaller game tables anyway.
- The Tesla Destructor got a massive buff going from Assault 4 to Heavy 10 and 36″.
- For the Death Ray, GW took out a little bit of the swinginess that comes from random D6 profiles and made it D3+3 flat damage. They also gave it +2 Strength.
Moving onto the Night Scythe, here’s what’s changed:
- Maximum movement range also decreased by 10″ across the board from 50/40/30
- Tesla Destructor profile buffed to Heavy 10 and 36″ again.
Necron Tomb Blades
