devourers do not bite necrons

had a match where my devourer was with its mouth around a necron cruisers (or BC they look the same) tailsection for a looooong time
and it never bit down
same with the cairn
had 3 devourers with their mouths clipping into its model, none of them where biting and they didnt do the bite damage
just the pushing damage

same happened vs marines
had it in their mouth for a long time
no damage, no bite

as if the strictly better and more numerous tyranids needed even more advantages

armor 2 hard the devourer is afraid of the dentist.

Hard to eat cans without a can opener. Otherwise the Devourer might be all bark and no bite.
