Voln Armor has been updated to no longer outright block Ensorcell (735). Instead, it has a significant penalty, but allows for higher skilled Sorcerers to overcome. As a somewhat thematic opposite of Cursed Armor, this is how both armors now work:

Voln Armor: +50 Sanctify (330), -100 Ensorcell (735)
Cursed Armor: -100 Sanctify (330), +50 Ensorcell (735)

Agreed excellent update and I second the allowing certain metals to have a better chance to be ensorcelled. I had some armor made ages ago with Krodera and it has an impossible penalty. I can't seem to part with it so it will forever be un-ensorcelled. <sigh>
