" In the lore samples included in the two codexes I have (4th and 5th) it mentions, time and again how easily necrons self repair themselves. In one section an ork Waaagh fight a force of necrons and even when the warriors are smashed as small as the warboss can smash them and when pieces are washed out to sea they still manage to self repair themselves and keep killing off the orks until a group of monoliths finish them off."

Necrons need their parts to regenerate. Orks tend to lop off limbs, which isn't hard for Necrodermis to reconnect once more. Energy weapons and Boltguns, on the other hand, deal enough damage to Necrons to stop them from regenerating. Anything powerful enough to smash open completely their chest section will stop them from regenerating and they will phase.

The codex doesn't mention them smashing them as small as he can smash them, and there were very few Necrons that did manage to repair under the water. Nowhere even close to the one in trillion you stated.

If you read the Fall of Damnos, you can get a more realistic basis on how good Necron regen is.
