With ref to the saves. Some weapons like the Necron weapon fitted to the piriars (not spelt correctly)or necron lord clearly stat no save or inv save. So for any weapon physical or mental to do damage it must state it. As to the cover save you could say that the animal life within the cover or shielding has a detrimental effect on the mind war giving the targeted enemy a cover save. As to the inv save this also could be argued that either by a device or special armour interups the potency of the psy attack. |
