Something I think is worth keeping in mind is that Mathilde is rather an exception to the norm, as far as magic items go. Like, this is not D&D, where past a certain level it's simply assumed that any important equipment is to some degree enchanted. No, this is Warhammer. It is a grim, gritty setting where magic is rare, dangerous, and frightening. Felix Jaeger, famed and experienced adventurer that he is, has one magic item. Abelheim, an experienced Witch Hunter, seemed to have none prior to his appointment as Elector Count of Stirland. Karl Franz, modern-day Emperor of Man with all of the Imperial Vaults to call upon, has two magic items. Powerful items, yes! But still,
two.
By Warhammer standards, Mathilde is already caked in magic bling. Seriously, she has magically armoured robes, a magic torc to make her a vision of terror, and a resurrection seed nestling inside her. If we were going by tabletop rules (I recognise we aren't, this is simply to illustrate the point) she would already have spent half again to twice her magic item allowance - and the way this vote is going, we're soon going to have a masterpiece dwarfish talisman of protection that would probably be worth that much again all by itself. There are plenty of seasoned Magisters who would count themselves lucky to have even one such artifact.
Again, Mathilde Weber:
caked in magic bling.
This is not a complaint, I should point out. Mathilde is an enchanter, who was appointed to high office by politics, and then presided over a major campaign. It is entirely fitting, and she has earned the right, that she is exceptional in this way.
But she
is exceptional.
Whom we are commissioning item from have little bearing on to what is required to make dedicated antimagic item.
That's nonsense. Making magic items is artisanal work. The skill of the artisan
absolutely has bearing on what's possible and how easily it can be done - it's probably the single most important factor.
As for items that makes mages safer available to armies... I am not so certain. Mages can do dispel. They can do shields. They can have tools to help with magic. But antimagic? As far as I know, it's a thing exclusive to dwarves. It is their speciality, the advantage they have in exchange for being unable to cast magic human way. They are people of stone. Strong, unyielding and down to earth.
So sure, there may be items that helps - but as far as I know, there is none that can deal with miscasts.
You are wrong. I cracked open my books and checked before writing the previous post. They exist and they are common, insofar as
any magic item is common (again, they aren't); they're generally in the 20-25 points range. Like, do you want me to quote the item blocks for you? 'Cause, I can do that.
Again, 'antimagic', insofar as that's a thing, is not unknown. Knowing how to dispel and ground hostile magic, whether your own or that of your enemies, is just part of being a spellcaster. Heck, dwarfs aren't even
that resistant to magic (it's just +10 on checks in the RPG, and zilch on the tabletop), they've just got Runesmiths who learn to be especially good at dispelling magic.
