- The Masterpiece and Paragon Cold Iron Rune versions are falsely flagged as armor runes. This is a bug and for pc users there is a third party mod which solves the problem.
- The Masterpiece Cold Iron Rune, as an armor rune, does not properly apply it's effect, thus rendering it useless. If it worked however, it would grant +12 damage vs. undead.
