Grandmasters Kassadin Guide by Yasukeh 11.1

By Yasukeh
Hello everyone! I am Yasukeh. Kassadin has been a pick that I have played consistently since season 3. At the end of Season 3, I stayed up for 36 hours and drank 20+ 8 oz. Redbulls to hit plat at the end while spamming Kassadin, and I did it with just a couple hours to spare..

Kassadin is a champion that greatly rewards game knowledge, your skill on the champion will rapidly increase with more time spent into the champion. Knowing the amount of damage you can put out, and when you can hop into teamfights will make or break your success on this champion.

I'm creating this guide to help you all have as many tools as possible to help you become successful on one of the most rewarding champions in the game to play!

I have peaked 356LP Grandmaster as of Apr 1st, 2020.

If you would like to check me out elsewhere, You can find me at:


I will be continually updating this guide to add more information, such as Matchups/Mid game/Late game/other builds/etc. soon, along with making the guide nicer to look at in general. Stay tuned!

If you have any questions about anything in the guide, don't hesitate to hop by my stream and ask! If I'm not streaming, I can answer any question on discord!

Kass has been nerfed several times in S10, for no justifiable reason. They aren't enough to make him weak in the situations in which he is strong. Play him in good matchups, and dodge bad matchups..
Preseason thoughts Back to Top
This is one of the worst times for Kassadin. The removal of Rod of Ages and the lack of shield on Seraph's Embrace effectively remove over 1000 health from your build, and there isn't anything to replace it. He is one of the lowest winrate Midlaners in this season so far, sitting around 40% winrate or lower, depending on the elo. This was made worse by the constant unneeded nerfs Kassadin received in Season 10. None of the Mythics are particularly good for him, and other champions got exactly what they wanted, especially AD Assassins.

Perhaps there is some unknown build that makes Kassadin busted, and I will be updating this throughout the preseason as new builds are found. Kassadin will likely be receiving buffs soon to make up for how weak he is currently. As it stands, I would recommend playing other champions in the meantime until Riot does a pass on Kassadin.

Kassadin is significantly weaker early, his item spikes come in later, his item spikes aren't as strong relative to others, and he is much squishier even after spiking, especially with all the extra damage everyone does.


This change greatly increases his beefiness, and somewhat makes up for Rod of Ages being removed.

Making the ult cost less mana somewhat solves the issue of there being fewer viable mana options to buy. Kassadin is still weaker than he was last season, but he is definitely playable in the right situation now, as opposed to never being good.

This change makes stacking tear much easier, and allows you to complete it at roughly the same time as S10. Starting Tear is still bad, and this makes getting it on your first or second back much safer, since it takes less time to stack.

Overall, I think Kassadin is still somewhat weak, but he can still be very strong given the right matchup.

Back to Top

Fleet Footwork is the keystone that synergizes with Kassadin the best. He has a rough time actually getting into the game, and the sustain gives you time to scale up and be able to survive laning phase. The keystone works particularly well with Kassadin, since he is a ranged AP champion. The AP scaling on the rune is very generous, and melee champions don't have the penalty where healing on minions is only 20% effective. You can easily end up healing 300-400 per proc with Fleet late game, which is a very nice boost to your survivability. The Movement speed is also very useful for you to be able to grab a CS, and speed into safety before you can be harassed.

Presence of Mind keeps you topped off on mana, which is really important if you want to continuously use Max stack ults.

Legend: Tenacity is simply the best option in this tree, since you don't benefit from lifesteal or attack speed. Since Kassadin is so vulnerable to CC, this tenacity does end up being very useful.

Coup De Grace is universally the best rune in this set for virtually every champion, and will give you the most damage. It lets you burst people down, and helps you finish off kills.

Taste of Blood is simply another source of sustain to keep you healthy enough to farm safely. This also incentivizes you to poke and trade, especially when they are trying to trade with you, to make use of the shield.

Ravenous Hunter gives you a very healthy amount of sustain from damage, especially when paired with Rod of Ages. The stacking mechanic also heavily gives you the incentive to roam, since it impacts your sustain. When you don't have stacks, try to show up to as many fights as you can to get those stacks started.

Electrocute is a page you would take if you don't need to worry too much about surviving, and instead think you can play aggressively. This page paired with Ignite and the Nether Blade buffs make the amount of damage you can do in early trades come within lethal range. If you aren't against someone who can push you out of lane, I would highly recommend taking this page.

Taste of Blood gives you extra sustain when you trade, and this page trades frequently. This bit of sustain comes in handy especially when you aren't opting into Fleet Footwork. If you want to fully spec into aggression, consider taking Sudden Impact, as this rune gives you pen whenever you flash and ult, which gives your more damage on your full rotation, making it more likely you will one shot someone.

Eyeball Collection is simply the better damage rune, and doesn't require any specific mini games for you to have damage.

Ravenous Hunter gives you spell vamp, which is incredibly good on a champion who does a lot of damage. You can be very healthy late into the game if you get low in a fight just by attacking a wave or some jungle. Don't consider Ultimate Hunter, as it doesn't give you nearly enough benefit, especially since your ult is already on such a low CD.

Option 1

Absolute Focus gives you more damage when you are high on health, which is generally going to be every time you start an engage on a fight. This also gives you a bit of extra power when going for early kills.

gives you just a bit of extra damage which could let you hit lethal much earlier when going for early kills.

Option 2

Presence of mind's Season 10 rework makes it a must have on Kassadin. It gives you 100 extra mana every takedown up to 500 Mana, which is a lot of free mana to get, and gives you much more leeway when it comes to ult usage. Your damage also scales from mana, so you get more damage every time you get a kill up to 5.

Coup De Grace gives you extra damage when finishing people off, which provides a very healthy amount of damage during every part of the game.
Items Back to Top
This will be updated soon for preseason. Items are shown above, with explanations aswell.

Starting items

Dark Seal is a much more effective start for you compared to other champions. We have much more of a need for mana compared to other champions, and this item gives flat mana. This start also allows you to start Refill Pot, which is great for consistently keeping up sustain, without having to sink so much money into Health Potions.

Doran's Shield received a fairly significant buff in Preseason, as you gain much more regen from it when being attacked. It makes this much more attractive into ranged poke matchups, and Paired with Fleet Footwork should allow your health pool to outlast most champions mana pool, giving you a much safer laning experience.

Take this if you need more sustain, it still provides a bit of damage, and keeps a low profile in your inventory. If you are behind, consider getting a Dark Seal, which will increase the amount of sustain you get from this item.
Patch affects Back to Top


This is actually one of the biggest buffs to Kassadin in a long time. For the past year or so, jungle has been largely decided by who is able to get early scuttle crabs, and mid priority was a large part in getting that. If your mid can't rotate to help you, you are put very far behind for the rest of the early game.

Kass virtually never has priority early, but now since lvl 1-3 priority doesn't matter as much, he is in a much better spot relatively, since you aren't putting your jungler behind just by existing..


30 extra damage on Nether Blade is an incredibly powerful change, that makes Kassadin incredibly scary on this patch, especially against certain matchups. This change gives you kill potential in lanes you never otherwise would have had kill potential. Pairing this with Electrocute means that your early game damage and potential of winning early is incredibly high. This change means I'd recommend taking Electrocute in any matchup you don't absolutely need the sustain from Fleet Footwork in, which doesn't come often.

9.23 Preseason

This change to minion XP makes it much easier to hit your lvl 6/11/16 spikes. With every ult point, you become much stronger, and this change gives you more incentive to sit in a side lane and farm. Learn how to Freeze In the above video:

More HP Regen over a shorter amount of time for Doran's Shield makes it a much more attractive item for you. This makes harder poke matchups much more safe, and allow you to survive any poke matchup you run into. Take this when you aren't confident in the matchup you are given.

Presence of Mind is a must have rune now. You get 100 mana every takedown, up to 500. This gives you not only more damage, but also gives you a much more forgiving buffer when it comes to ult management. There is no reason to take Triumph when this rune exists in it's current state.

This nerf is arguably fairly justified. The Null Sphere nerf is going to make it harder to farm from a safe distance in lane, and you are going to be less even getting out of laning phase with most champions.

The W nerf will make it harder to manage your ult stacks in late game teamfights, so you might have to worry about running out of mana. This shouldn't be too big of an issue with Presence of mind, but just be aware of it.

Overall, this nerf was totally unjustified, Kassadin's performance in solo queue has not been so out of line that he needed to be nerfed, but it shouldn't hit you too hard.


I genuinely don't understand what Riot was thinking with this nerf. Kassadin is not in a spot at all where he needed to be tuned down. He wasn't performing overly well in solo queue, and is non existent in pro play. 5 MS does turn out to be a lot over a long period of walking. This means you have to learn the new range of what it means to be safe in lane, where you can walk back to your turret if they attempt to gank you. It doesn't break Kassadin, as he is still strong in the specific matchups he is good at. Don't let this deter you from picking him up.
