A fun and exciting Mordekaiser builds you can try after the buffs (Includes Masteries and Runes)
is your first option. The slow is very helpful and it helps the slow down when being chased or chasing. Health is also good for your abilities.
Your 2nd option can vary between
boots,
boots
boots, depending if you want attack speed to proc Q faster, magic penetration for penetrating or Ionian boots for lower cooldowns.
for the extra-helpful movement speed, AP and the "tons of damage" echo passive.
4th item might be strange, but it's rally helpful in many situations.
. Why? Because 20% cooldown is super duper helpful, attack speed for Q and passive and 80 AP.
5th item,
. Helps with the Health regen, tons of magic resist, Health, cooldown and passive.
6th item
. Alot of Health and armor, and helpful passive to escape or engage.
If you want to sell your boots, sell it and get an Ohmwrecker
. If you had Ionian boots, your still getting 10% cooldown, maxing it to 40%. Also has Health, Health regen and Armor.
At the end, you will have more than 3500 HP, more than 350 AP, more than 200 armor, more than 120 magic resist, and tons of Health regen (300%). You can still deal tons of damage, while being tanky as a bruiser.
Onto Runes now. This is my personal set up which leads to personal success.
3x Quintesseces of Ability Power 6x Marks of Attack Speed 3x Marks of Magic Penetration 5x Seals of Armor 4x Seals of Armor per level 6x Glyphs of Magic Resist per level (can be changed to flat MR if playing against AP champions) 3x Glyphs of Ability Power
Masteries:
Stormraider's Surge is the new OP keystone mastery for Mordekaiser. Believe me, you can burst any champion's 30% HP at any point of the game for 2.5 seconds. That sexy movement speed + imune to slows for 3 seconds will help him sooooooooo much!
The rest of the set up is 0/18/12.
On the cunning tree, focus the following (in order): Savagery, Assassin (in solo lanes) or Secret Stash (duo lane), Merciless, Bandit (works even if no one kills the minion [if you miss it] and the 10 gold when hitting the champion), Precision and Stormraider's Surge.
On the resolve tree, focus the following (in order): Recovery (super helpful early game), Tough Skin, Veteran Scans (for early game) or Runic Armor (for health regen) and Perserverance (another super helpful health regen for early game)
Ok I hope you like my guide for all you Morde players and Morde mains (looking at you Malicious Metal), as of this patch, Morde will be back
