Right.

Only if the item passives have the same name they don't stack...even if the passives are from two different items. (e.g. the passive Magic Penetration form "Eyes of Pain" does not stack. So it doesn't help you Magic Penetration if you buy Haunting Guise and Liandry's Torment. You won't get more than 15 Magic Penetration.)

But since Gunblade's and WotA's passives don't have names they stack with each other.
