Why would i want a 25% damage buff for 770g? :/

Arguably, the 20% Attack speed debuff is better than the damage reflection on Thornmail, because it applies to their whole team instead of just to you.

Why would i want to have a item that gives me 500 mana? (Frozen Heart). When i can get 1 more armor for less the price and a good buff (Thornmail)

you cant have a snowball item like mejais in your core build, sunfire should only be used by tanks who can stick long enough to a team fight, if you want armor buy frozen heart or zhonya hourglass, im not voting tho

#1: You dont get Mejais for Mordekaiser.

#2: You'll not last 2 seconds in a fight with such builds. There's virtually no defense.

#3: The guide lacks images. Try to use codes and colors.

#4: There's no way to recover HP with those builds. Try to get Force of Nature before (3rd item) or Hextech.

1. Yes i know about the Mag pen runes and I', about to change that
2. Read the guide before you comment, I said flash is a good option and i also took Ignite?
3. I think it's a big waste of items slots, since I dont really need the Dmg and lifesteal. And if you play Morde smart you wont kill yourself with your abilities.
4. As I said, i like to take mid so i get the farm alone. But apparently I need to be more clear about that.
6. I will!

Thanks for the feedback!

TROLOLOL: One stun, and your done, son! (true is it not?)

Contructive: Morde needs someway to regen his health thoughout the game or else he will just has to press b every 3-4 minutes effecively harassing himself to the grave.

My 2 cents of how to make this build better:
1. Make you rune choice actaully mean something, Morde is not a pure tank he is just a super beefy caster. So Magic pen marks, Magic pen quints or Movement speed quints, Flat health Seals and Either Magic res per level/cd/Flat Ap glypes depending on what part of the game you want to be better in Late/6+mid/Early.
2. Get an escape kill with your summoners since morde has non and deperately needs one if going Ap. Flash is my skill of choice but many people like ghost also. The Ignite is perfect for morde
3. Add Hextech Gunblade or will of the anceints to your item list as the item you get first or after boots. I like the gunblade because i allows me to get in range with my skills, regen a ton of HP with my ult, Not harass myself while farming. Solo dragon when i get it.
4. Always go mid or top lane because Ap morde is the Ap carry of the team and needs the farm and is a great 1v1 fighter in ranked and without the exp mastery he will be so underleveled in a dou lane that he will never impact the game.
5. When you build deathcap build voidstaff also so that you do consistant damage to everyone and everything. You can also not build death cap and just build magic pen items like abysall scepter sorc boots and be fine for the people that you should be ulting/targeting aka AD ranged carries.
6. take a look at this build Hextech Gunblade, [sorc boots/ Merc treads, Abysall Scepter, Thornmail, Rabadon's Deathcap, and Deathfire Grasp and let me know how it works for you.
