So the Cygor gets to reroll all hits against models with a Ward save. Hand Weapon and Shield confers a 6+ Ward save. There was talk of this when rumours of 8th Ed. was floating around, but they were quickly dismissed because it was believed that the parry save didn't apply against monsters. However, as far as I can tell this is only true against a monsters Thunderstomp hits.

So, the Cygor single minded hatred against everything magical extends to anyone foolish enough to pick up a shield and a pointy stick at the same time. Which is ... silly.
