This is my very first build. Mordekaiser is one of my favorite characters in League of Legends and I decided to share my build with all of you. Hope you like it. :)

I appreciate constructive critisism and I'll try to improve and expand this build later on. Please do vote and comment as we will all learn from it. Also please think twice before downvoting. I'm taking all of the feedback with me and I'm continuously trying to improve this build. I'd appreciate and prefer constructive feedback over some random downvoting without any feedback at all. Thank you.

Also please note that I'm announcing upcoming changes to this guide at the end of the guide. Please read those first before commenting something that's already stated over there.

How I play Mordekaiser

This is how I play Mordekaiser; as a tanky caster.

A lot of people consider Morde a tank. Since Morde doesn't have any lifesaving skills like a taunt I simply don't see the point in tanking as Morde. People will just ignore you, kill your team and burn you down after. If you want a tank you should pick Rammus or Shen. I'm not going to argue about this anymore.

Pros / Cons


- Strong caster while not being squishy due to his passive's shield
- Strong solo-laner
- Strong lane-pusher
- Awesome farmer
- Easy harassment skills
- Healing ulti which supplies you with an extra teammember after a kill; a Garen-teed victory in a teamfight!
- Fun and easy to play


- Has no CC abilities
- Really needs HP regen early game because of his HP consuming skills
- No escape skill which makes him vulnerable to ganks
- Often pushes lanes too far early game, thereby calling ganks upon himself; this depends on your own insight

Greater Seal of Vitality

Since Morde's AP ratios are very low you shouldn't bother getting yourself AP runes. Here's what I like to use for Morde.

Greater Mark of Magic Penetration x9 - Gives you extra MP which will help with dealing more damage.

Greater Seal of Vitality x9 - I consider it a waste to use utility runes in defense runeslots. That's why I go with HP runes. You could change these for armor or flat HP runes if you'd prefer those.

Greater Glyph of Cooldown Reduction x9 - CDR is what Morde needs to put out his awesome spellcombo more often. A lot of Morde players consider these runes a must.

Greater Quintessence of Scaling Ability Power x3 - And yet more CDR. You might want to go for MS or HP, but I prefer CDR quints.

I'm playing with 9/0/21 masteries.

Those 9 points in offense seem pretty obvious to me. Grants you with 15% MP which is very usefull.

Why did I go for utility instead of defense? Because of the CDRs. It allows you to use your skills and your Siphon of Destruction - Ignite - Children of the Grave combo a lot more often. This should prove very usefull in game.

Your most common build

+ / / /

Core Build

This is your main focus when building Mordekaiser. This gives you overall survivability which is what you'll need if you want to stay out on the battlefield for as long as you wish.

I pick Force of Nature for it's MR, HP regen and MS bonus. I pick this item over any other MR item for in Morde's core mainly because it gives you just that little boost of MS you need to chase down your enemies. You should always be getting Negatron Cloak first since it builds up MR which a second Regrowth Pendant does not. NOTE: If you're playing vs two AD champions in lane you might want to swap this with Frozen Heart for some armor instead of MR and get Force of Nature later on.

I pick Frozen Heart for, of course, its armor and also for it's 20% CDR. I used to have Thornmail in my core build, but Frozen Heart's CDR proved to be of better use, especially if you're not playing against at least 1 or 2 AD champions. I do however find Thornmail to be more viable than Sunfire Cape because it will simply apply more damage to your AD enemies when you're being attacked.

Up next: AP

Now that you've got yourself some decent defensive items you'll want to be able to seriously hurt your enemy.

First of all I'd always get myself a Rylai's Crystal Scepter first. It gives you a small HP boost, alright, it gives you some AP, cool, but best of all is that it has a passive slow which will, in quite a lot of scenarios, prevent your enemy from escaping your clutches. Great item.

Second I pick Abyssal Scepter. It provides you with AP and a little boost in MR which should help you both with surviving and damaging. Last but not least Abyssal Scepter sends out an enemy's MR deminishing aura of which your whole team benefits. All together a great item for Morde.

For exceptional roflstomping!

Do you happen to find yourself in such an exceptional situation that you're totally facerolling the enemy's team then you might consider getting yourself a Mejai's Soulstealer and Rabadon's Deathcap. Pick up the Mejai's after you bought Thornmail and finish your build with (6th item) Rabadon's Deathcap instead of taking an Abyssal Scepter. You may also give up Rylai's Crystal Scepter but I personally prefer not to. Mejai's Soulstealer and Rabadon's Deathcap will let you dominate the game even more easily. Whenever a teamfight breaks out you should burn down the enemy's carry ASAP. Clean up the others after you're done and win the match. Easy victory. Please note that this is a very exceptional situation and that you should not always be recklessly buying a Mejai's Soulstealer.

Situational items.

Isn't this game over yet? Still having some issues with the heavy damage your enemy is dealing? Then these are some situational items for you.

Need a little of both MR and armor? Pick Guardian Angel. It comes along with a reviving passive which might come in handy in a teamfight you are currently losing. Since Guardian Angel gives both MR and armor (so you will only need 1 itemslot) and a nice passive I consider this a great item.

Do you need more armor? Then you have two choices: Randuin's Omen and Thornmail. I usually pick Thornmail when fighting against 2 or 3 AD enemies or when I'm fighting enemies like Tryndamere. If this isn't the case then I'd advise you to pick up Randuin's Omen. Its active skill can slow down the entire enemy team for a short amount of time. This one skill could greatly change the output of the fight. It also has some nice passive skills; Chance to slow the enemy on being hit yourself, 5% CDR. All together a great item.

Are you being burned down by a heavy CC team and do you need more MR? Then you'd want to pick up Quicksilver Sash. It grants you with more MR and an awesome active. It's active skill removes all debuffs you currently have which works even better than Cleanse. Very usefull item. I pick Quicksilver Sash over Banshee's Veil also because of it's passive. You cannot activate Banshee's Veil yourself while Quicksilver Sash can really save your *** whenever you decide it's going to save you. Quicksilver Sash also removes all debuffs instead of just one. Quicksilver Sash wins.

Walking through the game

Regrowth Pendant
Start off with a Regrowth Pendant. You really need this to stay alive because of your HP consuming skills.

Health Potion
Grab a potion as well just to be save.

Boots of Speed
Just plain boots. You could use the extra movement speed by now since others are getting more MS as well. Why not directly go for Sorcerer's Shoes? You don't need the extra MP just yet. FoN is of much greater help for you.

Negatron Cloak
The extra MR proves itself much better than an extra Regrowth Pendant.

Force of Nature
Great item for Morde. It gives you HP regen, MR and an extra MS boost. This also compensates very well for your HP diminishing skills.

Sorcerer's Shoes
Finish off your boots. The MP is a must for Morde since your skills will be dealing more damage with it.

Glacial Shroud
CDR over a small amount of armor. Don't pick Cloth Armor first.

Frozen Heart
Where other people buy Randuin's Omen, I like to buy Frozen Heart. I consider the CDR from Frozen Heart a must. It enables you to use your ultimate a lot more frequently which has proven itself a lot more useful in teamfights since you can get a ghostpet every battle. I'm not saying that Randuin's Omen would be a bad pick, I just pick Frozen Heart over it.

Mejai's Soulstealer
I like to get a Mejai's whenever I get extremely fed. It helps you to get that extra attack boost. NOTE: When you get yourself a Mejai's, please note that you should be getting a Rabadon's Deathcap as well later on. Also keep in mind that this will cost you your Abyssal Scepter. Only get this when you get fed! Skip this step if you are not. Don't bother getting a this item when you know you're not going to get a stack of 20.

Rylai's Crystal Scepter
The combination of extra HP, AP and a ranged slow work great for Morde. I consider this a must have on every Morde build.

Abyssal Scepter
AP, MR and a teamhelping aura. Grants you with attackpower and survivability which works perfectly fine.

Rabadon's Deathcap
Finish your heavily fed AP build with Rabadon's Deathcap. This item gives Morde that extra damage he needs to really shine. The AP + passive are just awesome on morde. Ult + Ignite and watch your enemy die because of your awesomeness! NOTE: When you get yourself a Rabadon's Deathcap, please note that you should also have bought Mejai's Soulstealer. Also keep in mind that this will cost you your Abyssal Scepter. Only get this when you get fed! Skip this step if you are not.

Guardian Angel / Thornmail / Randuin's Omen / Quicksilver Sash

Situational stuff, good for your sixth itemslot. Are you being burned down by a heavy CC team and do you need more MR? Then you'd pick Quicksilver Sash. Do you need more armor? Then you'd pick Randuin's Omen. Need more armor and could you use a counter to that ******* fed Tryndamere? Pick Thornmail. Need a little of both armor and MR? Pick Guardian Angel.

Skills / Skill Sequence

Iron Man (passive)

This is what makes Mordekaiser unique. He is the only champion who can continuously charge up a shield by damaging others. One of the best - maybe THE best - passives in League of Legends.

Mace of Spades

I consider Mace of Spades the weakest skill of Morde, but it's excellent for finishing of creeps. The biggest con is that this ability is bonus damage to your autoattack which means that this skill makes you very vulnerable to CC. The reason why I level this skill at the end of the game is because it isnt as reliable as Morde's other skills as stated before.

Creeping Death

As far as I know the only damaging shield in game, thus a great ability! This ability gives you bonus defense and deals damage per second to enemies and creeps around you which charges up your shield. The best part is that the shield is targetable. Cast it on a creep and stand back as your shield charges up without you doing anything. How cool is that?

Siphon of Destruction

This is the skill you will be using a LOT. Morde's main source of damage, that's why this skill should be maxed out ASAP. Low cooldown, nice range and cool damage make for a very nice ability. And, as any of Morde's other abilities, this ability also charges up your shield. Cast it upon one wave of minions and watch how your shield insta-fills!

Children of the Grave

'Hueheheheee...' How I love this ultimate. Instant lifesteal at a percentage based amount of damage. And as if that isn't enough it also deals the same amount of damage + lifesteal over the next few seconds. This ultimate works perfectly well with ignite. You'll just hope for no Quicksilver Sashes on the enemy team.

Guide Top

Summoner Spells

Whenever your enemy is under 50% health: Rush towards them, Siphon of Destruction -> Ignite -> Children of the Grave -> free ghostpet. Ignite makes it even more impossible for your enemies to escape you. Be sure to use ignite before your ultimate since your ultimate has a bigger range. This prevents you from ulting without being able to ignite.

Since you don't have any escape skills I consider ghost a MUST. You can either activate it to run your *** out of there or chase the enemy down. Great pick.

Results Screenshots

I'm currently running some testgames with Frozen Heart in my core and Thornmail as situational item and I gotta say that the CDR is great. I was able to use my ultimate in every, I repeat, every teamfight which made a huge difference overall. Here's the result of my latest game. It lasted 1 hour and 1 minute and we won.

Here are a couple of wins from me using this build. As you can see it also works well in Ranked. I had some games in between playing as Cho'Gath and Warwick so I had to cut up a little.
