The Armor also requires narrative screentime to be relevant. If we do not get into dangerous fights, the kind of fights that might have been lethal without it the armor is pointless. If we get into those fights, but roll well enough not to need it anyway it's useful as a safety line but doesn't show up in the narrative.
It's going to change the rolls dramatically, I think.
Also, I am decently sure it would not have been de-activated by Khorne in a battle with his champion like when we fought the Kull encampment.
There are a bunch of horrible wars lined up to try and reclaim some nexuses and Karaks, not to mention the oncoming Everchugging train.
I think it would be like adding wings to a tiger in its help towards Matilde either helping or just making the wars actually winnable.
Deep infiltration or deep scouting is much more feasible when getting caught does not mean you are de facto dead.
Matilde with her battlesword has a DPS that is really good, but she is restrained by her need to avoid getting hit. If she does not have to worry about getting hit by mooks, then it fundamentally changes any battlefield, because if she can figure out where any enemy leader or officer (non-mook) is, she can take them out. It becomes a battle of information and mobility which is one Matilde is uniquely able to handle.
Adding an unbreakable (by mooks) defense, makes it so that she has a much easier time disrupting enemy formations or logistics or anything, really.
A Bright wizard using the armor of Von Tarnus is nice. It turns a normally relatively squishy powerful artillery piece into a hard target. Super nice to have artillery protected that way.
Matilde or
anyone who can teleport,
using a weapon of similar quality as Matilde does and who has the
resistance to spells/magic that Matilde does, having the armor of Von Tarnus is ever-so-much-more than just well-protected artillery.
