It should be in the FAQ, but I don't have one :)

I'm about to make a Passion runeword.
It will have +1 Zeal nad +1 Berserk for any character, as it is stated in the description.

Questios is, will +Skills and +Paladin skills (Guardian Angel, Steelclash) items increase this +1 to Zeal?

Same for +Barbarian skills.
Same for Heart of Wolverine charges.

Zeal 1 is not as useful as say zeal 5 or 6, which I might have with my other items.

Thanks. :D
