Quick Hero Armor Question!

i want to know how to get my hero's head piece for 1 of my guys skills like for my mm i want it to be death magic but it only says for items attributed... and where can i get hero armor thxs

yeah i had the same problem at first

simple solution to it though, when you add a rune to the headpiece it then becomes +1 to that attribute

so +3 death magic rune into scar will make it not only +3 but will turn it into +1 as well
