When Mordekaiser's health falls below the cost necessary to use a skill, his health will drain to 1 HP. Any subsequent spell casts will bring him down to 1 HP, meaning that he cannot kill himself through his own abilities.
It is often a good idea to farm conservatively early game, as your Iron Man shield is not nearly as effective as it is late game.
Mordekaiser's best defense is maintaining his Iron Man shield by using his abilities. However, keep in mind that spamming skills will result in low health without enough health regeneration/spell vamp.
Iron Man is a great late game ability allowing you to survive during team fights longer than most other champions, as long as you use your abilities constantly.
The damage from a level 2 Creeping Death is a bit greater than the damage from Sunfire Cape but Sunfire Cape still gives more armor than level 5 Creeping Death . This makes it very effective at farming minions, and during fights. The bonus armor that it gives can also help tanking turrets. You can use it on an ally while staying in the back of the fight at low health to build up your shield and get assists.
Leveling up Siphon of Destruction first gives you the ability to poke at a range, but mind its health cost, as it can quickly bring you down below a comfortable amount.
Siphon of Destruction will not damage enemies behind terrain walls, even if the walls are thin enough. Also, it will not damage enemies on the opposite side of a tower.
Creeping Death is usually the best ability to gain shield health, due to its consistent AoE damage.
If you use Children of the Grave on their attack damage carry and take down the champion quickly, the ghost's auto attacks will fill your shield up and help you stay alive longer.
The combination of Ignite and Children of the Grave is deadly to almost any wounded enemy.
Like most other secondary units, the soul you've stolen with Children of the Grave can be controlled using Alt + Right Click. However, unlike most secondary units, your ghost acts as an allied champion, and will be affected by abilities that can only target champions, such as Wish, Requiem, and Infinite Duress.
Children of the Grave can also be used to block Caitlyn's Ace in the Hole, the primary damage/effect of Ashe's Enchanted Crystal Arrow, or Graves's Collateral Damage.
Avoid casting Children of the Grave on champion clones or champions with death-preventing abilities (ex. Guardian Angel).
Try and wait until your target is fairly low health before casting Children of the Grave, as most people will run when they see they have the debuff on them.
If you are using Ignite, keep in mind that its range is much shorter than Children of the Grave, and so you should try to use it first.
Additionally, if you have the mastery Summoner's Wrath, using Ignite first gives a bonus 5 ability power, causing Children of the Grave to do more damage.
Mordekaiser's ghost will attract tower aggro first, but if it attacks a champion while you are in range, you will become the new target. If you cast Creeping Death on the ghost and it hurts an enemy champion, you will draw aggro instead of the ghost.
Mordekaiser is very capable of taking a solo lane against 2 enemy champions, reaching a higher level than both of them while effectively harassing and farming at the same time. If you harass them enough, you can potentially get a double kill with your ultimate.

Spell Vamp is a bit more complicated than Life Steal.

Basically if your damaging ability doesn't proc Life Steal (abilities like Mystic Shot, Double Up, and Parrrley do) then it will almost always use Spell Vamp, even if the damage dealt from the ability is physical or true damage. This means that abilities such as Reckless Swing or Feast (true damage) or Spear Shot (physical damage) utilize Spell Vamp.

Something to note about Spell Vamp, however, is that there are two different values of Spell Vamp. Single-target spells, such as Malefic Vision, Reckless Swing, and Spear Shot, have 100% effectiveness when it comes to Spell Vamp. In other words, if you deal 200 damage with these single-target abilities and have 50% Spell Vamp, you will be healed for 100.

However, multi-target abilities such as Tormented Soil, Incinerate, and Heartseeker Strike, have 1/3 effectiveness for Spell Vamp. If these abilities deal 200 total damage with 50% Spell Vamp, they will only heal you for 33, but if you deal 200 damage to 5 enemies (totaling 1000 damage) you will heal for 166 health.



According to what Kismet says, Siphon of Destruction Creeping Death and Mace of Spades (When there are multiple targets) are multi target abilities so you’re only getting 1/3. To take advantage of your spell vamp, you’re going to want to use Mace of Spades against one target whether it’s a minion or enemy champion. I will say that your Children of the Grave will heal a lot more than what it normally does. Spell vamp is easily a way to replace health regen. Every item that gives spell vamp also gives ability power which is very good. I encourage everyone to still buy Health Potion every time they go back to base.

Level 1 – Siphon of Destruction - E
Level 2 – Mace of Spades - Q
Level 3 – Siphon of Destruction - E
Level 4 – Creeping Death - W
Level 5 – Siphon of Destruction - E
Level 6 – Children of the Grave - R
Level 7 – Siphon of Destruction - E
Level 8 – Mace of Spades - Q
Level 9 – Siphon of Destruction - E
Level 10 – Mace of Spades - Q
Level 11 – Children of the Grave - R
Level 12 – Mace of Spades - Q
Level 13 – Mace of Spades - Q
Level 14 – Creeping Death -W
Level 15 – Creeping Death -W
Level 16 – Children of the Grave - R
Level 17 – Creeping Death -W
Level 18 – Creeping Death -W

Even though Siphon of Destruction costs the most life when used and was nerfed to not help generate shield anymore, it is still an important ability to have. It is your only method to harass when laning or to harass before a team fight. Once your AP starts going, you will notice a much larger amount of damage. Poking with it will get to your target.

A big reason why I chose Mace of Spades over Creeping Death is because it only requires one swing to get the full effect of Mace of Spades while it takes a whole 6 seconds for Creeping Death. I still use Creeping Death before I run in and fight for that extra armor and magic resist, but you’re going to want to hit and run, not stay in the fight until you die.
