Both Gunblade and Wota Spell vamp stacks. Please read this.

Okay i get this a lot during game play and a lot of people do not understand this. I am told many times that if i buy wota and gunblade together i will not get 40% spellvamp i will only get 20% spellvamp

Now everyone of these items have their own Unique passive. What people have told me over and over that unqiue passives DO NOT STACK. YES I AM FULLY AWARE OF THAT. THE UNIQUE PASSIVE IS ONLY ACCOUNTED FOR THAT RESPECTED ITEM, so I cannot stack any of the listed items below and give me double spell vamp. example > 2 x wota or 2 x gun blade.

THIS IS WHAT I CAN DO. BUY WOTA AND A GUNBLADE AND GIVE ME 40% SPELL VAMP. THEN I COULD BUY SPIRIT VISAGE Which has a unique passive: Increases self healing, health regen, lifesteal, and spell vamp effects buy 20%. which total up to 48% spell vamp.

And one more thing. Mordekaiser was the first champ I've played, since season 1. I've noticed a bug that i have filed a few times before and it still is not fixed. mordekaiser's q has a bug where when he swings his mace hitting a target striking up to 3 additional nearby targets. every so often that does not happen and i only hit one target near buy. there have been multiple occasions where i have died or failed to get a kill because it did not strike additional the additional target (minion / champion)

The picture i posted will explain the bug.
