Yes.

Yes.

Designer's Note: I have to hold my hands up for not spotting that allowing a Butcher or Slaughtermaster to take an ironfist, would also allow them to take magic armour. Allowing them access to magic armour certainly wasn’t my intention, and it’s something we’ll certainly fix when we do the next edition of the Ogre Kingdoms army book. However, after much debate, we’ve decided that it does not give the Ogres an unfair advantage, so we’ve decided to leave the rule as it is written for the time being. That said, I’d personally recommend that you avoid giving your Butchers and Slaughtermasters magic armour – doing otherwise goes against the spirit, if not the letter, of the rule.

When you deploy them.

Yes.

Every model in the unit must take one test.

Yes to both questions.

You check at the start of each round of combat. Any model in range at that point has the Always Strikes Last special rule for that round of combat.

For Example: A unit of 20 Empire Spearmen are fighting against a unit of 6 Ogre Bulls. 15 Empire Spearmen are able to attack the Ogre Bulls. 7 out of the 15 that can attack are within 6" of a Thundertusk behind the Ogre Bulls at the start of the round of combat and as such are affected by the Numbing Chill special rule. This means that 8 Empire Spearmen would attack at the Initiative 3 step. Then the 6 Ogre Bulls would attack at the Initiative 2 step. Finally the 7 Empire Spearmen in range of the Numbing Chill special rule will attack at the same time as the Ogres’ Stomp (assuming that there are at least 7 Empire Spearmen left alive).

Yes to both questions. He is, after all, Golgfag Maneater!

No one gets to keep that magic item.
