Until it's FAQ'ed otherwise they should probably have access if they have the option for an Ironfist ("works in exactly the same way as a shield") since shields explicitly grant access to magic armor.

It's probably something that should be discussed with your local group, though, since a lot of players have issues with wizards with magic armor and it's not explicit.

I noticed it doesn't let you take a Big Name and a magic banner on a BSB. The blurb about a BSB doesn't prohibit taking a Big Name and traditionally you have been able to add similar enhancements on a BSB and still take a magical banner.

BRB, pg. 500
"The only exception to this is when a Wizard has armour as part of his standard equipment or an option for 'normal' armour, such as light armour, or a shield."

Question becomes... is the 'ironfist' a normal item? Technically, it is a 'shield', but it does offer advantages that a normal shield would not. So the argument can go either way at this point.

No reason to include the item until FAQ stats otherwise IMO. If a person wants to add it, and gets the thumbs up from their gaming group, then they can tack on the points themselves in the meantime.

To many uniques Rules.
Keep getting this error message when making ogre armies.

1) Greedy Fist does not appear to be granting a +6 Ward Save. (The strength bonus is working as intended.)

2) A hunter on the Stonehorn can take both Enchanted Shield and Ironfist. I don't see any rules stating this is not possible - Ironfists don't preclude the use of shields (at least as far as I can see), but something to watch for in a future FAQ.

No that's ridiculous.

The option to use it should be included in the data files, and if people DON'T want to use it, they just have to not take any magic armour.

Your option creates needless work for thousands of people who want to use magic armour.

My option imposes nothing on anyone.

3) Ironfist stacks with Armour of Silvered Steel (supposed to make your armour save 2+, but cannot be improved). Looking at RAW, Ironfist would not improve armour save, but would still grant Parry save.

It looks like Skragg is missing an attack. He has a base 4 and should be +1 for two CCWs and another +1 for Frenzy for a total of 6.

Ironfist and Skragg fixed for next release.

4) Beserker Sword does not add an extra attack for Frenzy; it would be "permanent" as the sword rules state you can't lose it.
5) Lore Of Beasts: Savage Beast Of Horrors; Strength is misspelled. Yes, I know it is so darn trivial, but I noticed it just now... :)
