Hmmmm interesting take on the Omen VS F-Heart, thanks for the feedback :)

The health marks are not very usefull as they only give enough health to withstand half of a normal attack. The shield will only give you 3 extra hp which is not very usefull either. It's more beneficial to get magic resist pen. I am not sure you should put a frozen heart in the build since randuins omen can replace that easily. Malphite tends to stop needing his clarity with that which is a good thing, but hey you just wasted a item slot when summoner spell could take care of it. Zhonya is an item I never actually considered for Malph. It increases 3 of it abilities' damages.

yaa i tried to really get a good balance of defensive aspects while still getting that AP. idk ill try it out. thx :)

going magic pen marks and/or 9/0/21 or 9/13/8 will give you a lot more dmg while not having to build ap... i also tried going ap quintissences but that sacrifices a lot... works a lot better because he has only 2 spells that scale on ap anyway, it might even give you more dmg AND more defense than this build.
