I have changed some of the wording to hide and protect the source. Once again, please take these as rumors until we have the codex in hand. Only a couple days left.
your chaos fluff was right, as he was proofing the fluff for legions, and it is a very elitist army but there does appear to be cultists for the horde variant.
I was able to check over the Necron codex, since it was on his desk.
Entriopic strike is true however it requires a 4+to rolled for a hit to reduce a tank by 1AV and if a tank goes down to AV0 then its wrecked.
The deathmark stuff was right base unit 5 95points.
The monloith is 200pts.
Scarabs are 15pts a base with entropic as standard 4attacks 3wounds and they count as beasts now with fearless.
C'tan Shards are quite bad. Imotek's stuff was all right and he has a 2d6 range weapon thats str6 ap1 one shot.
the royal court was right, especially with crypteks.
The fliers doom scythe and the bomber variant are broken, with a 36" move and they can transport.
The ghost ark is in essence a portable res orb.
Necron immortals are worth taking over warriors with str4/5 (cant remember) ap4 rapid fire guns gauss.
Destroyers are a max squad of 5 with max heavy destroyer upgrades as 3 counting as jump infantry.
The new necron jetbikes llook insanely good in the artwork, shame about in practice.
