I was confused about this, and I couldn't find any information about this matter.

It might not be a big thing, but I wish this could be a good tip for others.

 

 

So Mail Armor has DR reduction calculation orders as below

 

Normal :

BASE 9×1=9   SLASH 9×1.5=14   CRUSH 9×0.5=4.5

 

Exceptional : 

BASE (9+4)×1=13   SLASH (9+4)×1.5=19.5   CRUSH (9+4)×0.5=6.5

 

Exceptional + Crush Proofed : 

BASE (9+4)×1=13   SLASH (9+4)×1.5=19.5   CRUSH (9+4+3)×0.5=8

 

Consequently, 'Proofing' enchants are always applied at first, so 'crush proofing' your mail armor might not be a good choice.

CRUSH-Proofing on mail armor only increases 1.5 CRUSH-DR, while SLASH-Proofing increases 4.5 SLASH-DR.

If you want to defend against CRUSH damage, you'd rather use other armors, like brigandine or plate.

Good post.

 

It's been beat to death in other threads, but the visuals help.

Thanks for the info, I had been wondering why proofing my Plate against shock damage did benefit so little.  Better use that enchanting slot for crush...as I am wearing the blunting belt.

Interesting enough, armors where mitigating weakness with proofing is best, are those that do not have weaknesses as such, but two +25% strengths, and 3rd physical protection without any weakness.

 

Like Padded and Plate. In those cases using proffing for slashing (padded) and crushing (plate) is great, since it adds full +3DR bonus, and as result you get all around great armor.
