Hi Federals, im from LAS, i have been playing Mordekaiser and wanted to ask about the spear of shojin, i know its a bug, but since riot didnt fix it, what do you think of this item on mord? The bug about you activate the passive of Mordekaiser (the third attack) with one ability and the spear of shojin will count the passive as a ability and stack the max ammount inmediatly.
Is it good or you dont recommend it anyways?
Sorry if i wrote something wrong, seeing you from Argentina!❤️.

I think shojin is mostly a bait item. It's not horrible but I think there's better items in most cases. If you want more dueling power you have Riftmaker, Liandry or Bloodletter's. If you want higher ability haste you have Cosmic Drive and that item gives you a lot of extra speed as well plus it's not just basic ability haste so you get haste value for your ultimate as well.

Hello, Federals.

I've been picking up Mordekaiser in the past few months after getting a really good hang on with Garen (partly thanks to your guide, haha) and just had two questions that you could potentially answer about certain scenarios with Mordekaiser:

1. After a few games against Conq. Garen, I can safely say he gets 100% stomped by Mordekaiser with your build in particular, but as I got higher up in rank, some Garen's were starting to take PR as usual and the lane in general was just super uninteractive at best because he would just proc it and run out of my Rylais-buffed AOE. Sometimes, he was fast enough with Stride active to run out of my ult range while I was silenced so I couldn't even hit him with it without burning Flash! Is there ANY change to your gameplan vs. Garen if he runs Phase Rush so you still have a big advantage (or at least reduce Garen's strengths with running PR vs. Morde)?

2. Some bruisers I went against would take the unusual route of 1st item'ing into Serpents Fang (Darius, Sett, Jax even) and while it was relatively ok in lane since they were SUPER squishy, it took a HUGE toll when teamfights started breaking out. That being said, if players start building Serpent's Fang early, is there anything that Mordekaiser can build or rely on other than his shield so that the shield cut won't take too much a toll on him? What should be my plan to mitigating the shield debuff? Build Spirit Visage to get a bigger shield so I at least keep more of it when it gets cut? Straight up focus on building HP/resistance items after maybe my first item? Just wondering how you deal with Serpent's Fang personally.

1. Yeah you still win it, you just gotta perma freeze basically and only fight him if your ult is up, otherwise you can't really chase him down, at least not most of the time. Either that or fighting him if his Phase Rush is on cooldown but most of them don't ever engage if it's not up.

2. If they rush Serpent's it destroys them, it's not a great rush item and it also makes them extremely squishy. All you really need to do is perma side lane and not teamfight. If a Jax or Sett rush Serpent's they are giga griefing their build. It also depends on the enemy comp, because sometimes you're forced to teamfight because you get beat on side lane. Serpent's is just a **** item to deal with as Mord.
One way you can increase your tankiness against it is by going for the Death's Dance+Zhonya's item combo. The stasis from Zhonya is really good but you can also use it to get the bleed damage from Death's Dance completely nullified because it will tick down while you are in the stasis but you won't take any damage, which means you're not forced to get a takedown to get rid of the bleed, and Death's Dance has a really good 30% damage taken to bleed conversion.

Hey, very informative guide brahski but main question: did you recently update the mordekaiser matchup spreadsheet and removed how you play the matchup against the specific champs? why is it missing/removed it was so informative about the matchups, about what to be wary about and even from level 1 trades to late game just wondering why it got removed
1
Federals1 (4) | October 7, 2025 10:58am
I did a collab with Alois and made a new Mordekaiser guide and as part of the agreement I had to remove the tips and tricks and put them in that guide. Nothing else was removed from the spreadsheet or the mobafire guide, but I had to remove the tips and tricks.

Why would someone go Void Staff or Cryptbloom instead of Bloodletter? Even before the item existed, I didn't know a single situation where these two were a smart purchase given that Mordekaiser needs to tank a lot of damage to be able to do his. Not to mention that the shredding from Bloodletter stacks with the passive %pen from E with the same formula that Black Cleaver uses to stack with the likes of Darius or Pantheon

Federals1 (4) | March 27, 2025 4:50pm
It's mostly done in cases where you'd play a very heavy AP focused seup to 1 tap people, usually paired with Rabbadon's Deathcap. With Staff and your E pen you have like 50% magic pen total. It's extrmely niche, and ever since Bloodletter's got added I don't think I've had more than like 4 games with either Void Staff or Cryptbloom, but it gives a lot of instant damage. If you Q a squishy with 80 mr, just from Staff and pen boots that target would have under 30 magic resist for you, and because you don't need to stack it like Bloodletter's it means the full pen is instantly applied from the very first damage they take. Other than that, you never really want to run it. Before you could do it if the enemy team had 3+ super magic resist stackers or if your team was heavy on magic damage so you needed to deal with heavy mr from the enemy team, but because Bloodletter's exists now it basically means you never need to do it into a tank as you can stack up Bloodletter's very easily vs them and it even has very good value for your magic damage dealing allies.

Makes sense, I can imagine it's hella fun to onetap the ADC with a build like that lol. Shame the current meta really doesn't allow to do that reliably, especially above low elo

I do not use an in game item set, so there's no link for that. I just have the items placed on the guide with the explanations and some builds for different cases.
