Bellow is a link to reference sheet for magic lores taken from Warhammer website (“Chronicles” section). It confirms everything I have written with the exception that Bane of forged steel may be also called Bane of forged metal... I am not clear on which one is correct.

I have also cross-referenced with magic cards posted on Warhammer website. The information is consistent.
