The ability haste guide to Mordekaiser

By Kokob5
About Mordekaiser
"You are going to Brazil!" - Mordekaiser, probably.

Mordekaiser is an AP juggernaut stuck in a weird spot between bruiser and duellist thanks to his Ultimate. However the lord of death is still a decent pick toplane with quite a versatile item selection and a kit that is quick and easy to learn.

What is an AP juggernaut? AP juggernaut's are similar to their AD counter parts, often building some damage items mixed with tank items in their builds. Hard to kill and dishing out tons of damage to everything around them if you find yourself inside Mordekaiser's Realm of Death you'll most likely come away with a grey screen, browsing the items you can't buy while you wait to respawn.
Pros and cons
Good 1v1 potential because of Ultimate.
Good snowball potential
Mordekaiser excels when getting ganked as he can turn it into 2 1v1's.
Ultimate is a valuable tool for securing objectives such as Dragon and Baron.
Hard to dive.
Steals stats with ultimate making fights you'd normally lose winnable
Built in %magic pen and %ms bonus
Ultimate always has value.

Mordekaiser is punished very harshly by Quicksilver Sash or champions that can undo suppressions.
He's Immobile.
Mythic itemization is limited and not that great.
Obliterate is the only source of reliable ability damage. The rest coming from passive and auto attacks.
Abilities are projected and easy to avoid.
Lacks hard CC.
Heavy/expensive items.
Some tips and tricks
Mordekaiser's bread and butter combo is Death's Grasp > Obliterate > autoattack to proc passive and run his enemies down with passive damage and deliver a beating with his mace.

Flash > Obliterate is a good way to finish off fleeing champions, just be sure they'll die to it or you'll have wasted Flash and made a fool of yourself.

When running Conqueror try to prioritize activating passive using an auto attack and not an ability or it's activation damage won't count towards your conq stacks forcing you to auto attack an extra time to activate it.

You can use Death's Grasp during Obliterate when it lands making it hard to see that they're about to be pulled in.

You cannot activate Indestructible during Obliterate, be wary of this when you're low during a fight.

If someone is in range you can use Death's Grasp and quickly cast
Realm of Death as it has a 75% slow making the E impossible to dodge unless they use a mobility spell to avoid it or have Phase Rush active.

You can use Death's Grasp to push enemies away from you if you need to escape quickly. Use it directly in front of you and it'll push enemies that walk into it back.

Avoid ulting targets that will likely die as you're just giving them the change to possibly escape and wasting your ultimate.

Obliterate is anchored to the spot you clicked on it's activation, beware of this before doing Flash > Obliterate or you might end up throwing it in the completely wrong direction.
About this build.
Inspired by the Master Mordekaiser player KaizerMorde, this build makes up for Mordekaiser's rather loose placement as a "Juggernaut" by making him into a true one that is a high threat in 1v1's and team fights, with the high ability haste offered by the build you'll be throwing out Obliterate every 2 seconds and Death's Grasp on a 5-6 second CD, this build truly compliments Mordekaiser's kit wanting to smash his mace over peoples heads over and over until you're marching down the enemy nexus.
Runes explained.
Conqueror is fairly obvious, it's a good rune on Mordekaiser adding in to his strength of a sustain fighting by giving him a little spell vamp and extra damage.

Triumph Is great on any champ. Especially Mordekaiser as he likes to take ganks in 2 separate 1v1's using Realm of Death.

Legend: Alacrity vs Legend: Tenacity Both are good and are situational, Alacrity is for when you need as much damage as possible in fights and some extra pushing power while Tenacity offers you resistance to CC heavy comp's later down the road.

Coup de Grace vs Last Stand Althought Coup de grace can be good usually during fights Mordekaiser will find himself low, especially after ganks, due to Indestructible Mordekaiser gets max use from last stand while still being relatively healthy.

Celerity is perfect for this build, it synergizes with not only your passive but also boosts cosmic drives movement speed making it easily the best rune to stick to the enemy while in death realm or in team fights.

Gathering Storm is used mostly because the other runes aren't that great, it helps that this build really turns on at two items and by that time you'll at least get some use of this and as it scales it'll make up for the tank items you'll eventually have to build to survive.
Itemization explained
Riftmaker: The mythic made for AP bruisers. It's not that great honestly but it's what Mordekaiser is stuck with for the time being. Due to it also being good on champions like Akali when it's decent the item has had it's power shifted towards the late game with half of it's omni vamp being locked inside the mythic passive.

Rylai's Crystal Scepter: Although the loss of Liandry's torment hurt Mordekaiser and Rylai's the item itself is still a fine buy with high stats that he loves and a 30% slow that'll keep the enemies in range at all times and makes landing Q easy.

Cosmic Drive: A great second item on Mordekaiser and essental for this build, providing extra movement speed and 40 ability haste with one item along with pretty good stats and Making keeping close to enemies easier during fights or for just moving around the rift in general.

Nashor's Tooth: Making up for Mordekaiser's low attack speed this is a great item on him when ahead, although this item makes you squishy with it's lack of defensive stats it's perfect for 1v1's in the death realm or for split pushing as Mordekaiser's ability to take towers without it is subpar.

Void Staff: Although Mordekaiser does lose some magic pen because his E's passive pen puts him past the soft cap it's still a great item against enemy teams or champions that stack lots of MR.

Gargoyle Stoneplate: A good pick up as a third or last item, offering a shield for 100% bonus HP every 90 seconds it's great on him, the stats are a bonus and much appreciated by a Mordekaiser against a mixed enemy team comp.

Spirit Visage: With it's ability to enhance shields and heals by 25% more than making up for it's low MR this item is a must have into any team comp that has a strong AP champion. A bonus is that it's enhanced by revitalized.

Banshee's Veil: A situational item against champions with hard CC that if it lands could probably end with you dead or forced to burn ult to survive.

Zhonya's Hourglass: A good item for mordekaiser offering decent stats and high survivability, just be careful about using it's activate as a badly timed one can cause you passive to run out, would recommend later in the game due to armguard not being a valuable first buy anymore after it's nerf.

Morellonomicon: You buy it the same reason mages do, can be replaced with Thornmail if you're against a team that auto attacks a lot and you're confidant you can land E when it matters.

Dead Man's Plate: Very situational, only buy if you REALLY need to move fast.

Rabadon's Deathcap: A great item, pure damage, a good buy when you're snowballing and want to keep crushing plebs with your mace to end the game quickly.

Randuin's Omen: A good buy into crit heavy teams, makes your 1v1 potential against champions like Yasuo great as the activate reduces their damage further along with ultimate.

Thornmail: A good buy into autoattack heavy teams, in match ups such as Aatrox and Fiora it's a good second buy after mythic due to you already buying bramble vest. Can be switched with Morellonomicon if need be.

Force of Nature: Good against AP champions that deal constant damage and in general a good item for Mordekaiser as the movement speed lets you stay ontop of people. I'd usually recommend this when Spirit visage isn't enough.

Demonic Embrace: Demonic embrace is a subpar item that synergizes with Mordekaiser. with a 1.2% HP burn and the bonus armour and MR you get from it being laughably low even in the early game. This item should only ever be built against teams with at least 2 high HP targets or if you're going a tank build. Otherwise you'll get more out of other items.
