So, from what I've FOUND on this forum, no one has any home-brew Necron stats. Please correct me if I'm wrong.
Firstly, to dispell the illusions of the optimistic, I have not made Necron stats. I am inquiring about them.
Also, SPOILERS FOR THE EMPEROR PROTECTS BELOW
Fortunately, my need for stats other than the Wraiths in a Stony Sleep are for the campaign AFTER the current campaign I'm running. I'm going to rework the Emperor Protects story-arc so that the Warp Gate is damaged, but not destroyed, and at first seems fine.
The next campaign begins when the gate starts behaving erratically - the damage is more than anticipated. On top of this, the Necron begin to awaken in the Reach. I figure that something already so thick with secrets as the Achilus Crusade could manage to keep a Necron uprising a secret, and pass it off as a local thing, believing the Dark Pattern has manifested itself, not that it is a sign of a galaxy-wide threat.
So, it turns out that there was a race known as the 'End Men' who were enslaved for the amusement of the C'Tan, as they have no warp presence, and thus wouldn't taste very good, but were brilliant and capable builders. So, the Deciever perhaps forced them into building the Jericho-Maw warpgate. However, the End Men correctly predict that they will be slaughtered after the completion of their task, and so modify Necron phasing technology, and phase themselves into a void existence 'within' the 'space' inside the Warp gate.
The Necron uprising is just too much for the Crusade if the gate is unable to reliably bring supplies, and so the first plan is to blow it up if a way to fix it is not found. Thusly the players must free the End Men and get them to fix the gate. Of course, they won't know of the End Men initially, and may end up with the parallel tasks of getting supplies for a bomb large enough to obliterate the gate to slow the Necron advance in case they can't hold them off (Freespace 2 style), as well as gathering the bits for the most skilled Tech-Magos and Inquisitorial agents suited to the task to try and bring the End Men back into real-space. The End Men are totally the grim-dark version of the Endermen from Minecraft. All of my players play Minecraft, and will be amused by the DED SRS interpretation.
ANYWAY that's why I need some Necron stats, or at least a basis for their weapons. I'm not too well read up on their exact capabilities, though I have Fall of Damnos, and could go back through that to determine how good they should be, but figured I might as well seek counsel with all the other GMs on here.
