How do I apply a Mark of Penetration?
Marks can only be applied to items that are level 20 or higher.
Ah. I saw that page, but didn’t realize what “(level 20)” was intended to mean — I thought it meant that I had to be level 20 . . . especially given the introductory sentence ending “used at (sic) any item with an upgrade slot.” Thank you for explaining.
Runes are often better than marks, so marks/talismans are better used on accessories and rings.
