Massadin Guide season 9 for mid lane! (9.17)

By Vispectra
Hello and welcome to my Kassadin guide! Allow me to first thank you for taking the time out of your day in order to read this guide, you can call me Kassaria. I'm a pretty hard-core Kassadin main ( Duh ) with roughly 850,000 Points on the champion. I've been playing him since Season 6 and still find the champion to be very enjoyable! Although I'm not the highest ranked player nor the best Kassadin player, I think I can provide some useful infomtaion on him to help you get started on playing him. Just don't forget that your playstyle might differ from mine and each and everyone has their own take on a champion ! It's up to you to find that on your own but in the meantime , I'll provide you with all the knowledge I've gained from playing this champion over the years.I found my love for this champion back when I just started league , I bought him with what little IP I had mostly because of reading his short bio at the time. He's a very unique assassin, so unique that some don't even classify him as one ! The fact that his ultimate is his lowest CD ability and his insane mobility later one make him a blast. This is my first guide ever I'd like to add , so if you have any suggestions or advice , don't hesitate!

+ Extreme scaling
+ Unmatched mobility with Riftwalk
+ Good Counter-pick
+ High carry potential
+ Pretty fun to play
+ Has a really hot daughter

Kassadin is a late game carry assassin/burst mage with a lot of mobility. He truly shines once he hits his level 16 mega spike and his items are completed! He's easily able to dive in and out of combat to take out high priority targets all the while remaining alive thanks to his Riftwalk due to it's very very low cooldown later on! He preforms very well naturally against Ability power teams due to his Void Stone passive reducing incoming magic damage by 15%.

- Very weak laning phase
- Heavily item reliant
- Very immobile pre-6 and can suffer from ganks
- Struggles against AD
- Very poor lane pressure
- Requires some time to get used to his playstyle

Now these are a few downsides about Kassadin. While he is a good counter-pick, he is also easily counter-picked. Most match-ups midlane are usually quite a struggle early on as your lack of mobility and mediocre range make you very easy to punish. Mages will typically auto attack you and harass you when you try to CS. You'll often find yourself shoved undertower and you are pretty easily ganked pre-6. He is also very item reliant and falling too behind will result in a very difficult game. Don't to expect have much fun in lane with Kassadin.
Back to Top
Electrocute is my favorite keystone on Kassadin. He's an assassin after all! The damage increase that Electrocute provides in the early and middle stages of the game are undeniable. It helps you out quite a bit during your laning phase in order to trade properly.
Fleet Footwork is also a viable option for difficult poke lanes or, if you want to safely scale into late game! It will provide sustain in lane and help you survive the laning phase.
Arcane Comet is also a somewhat viable option. With Arcane you will usually play like a typical mage aiming to poke your laner out of lane. While this page is not used very much , it is still an option.
A very very strong rune, not for the cooldown reduction on your ultimate but more for the missing mana recovery! It makes a massive difference in fights due to how costly your ultimate can be ( 400 / 800 mana ).
A fantastic rune for obvious reasons, the healing on an AP assassin can be quite massive , even if 14% doesn't seem like much, with the high damage output you have it will heal you for hundreds.

This is your go-to first item most of the time. Although it is possible to skip the RoA, it's a rather efficient item on Kassadin. It will scale with you throughout the game offering you a decent amount of health and AP once scaled. You'll ideally want this as early as you can finish it.
Archangle's staff is an item you can build first although it is overall, instead of RoA. It is a must have. This is because of the amount of mana you use. Your ultimate will drain your mana very quickly and this item helps refund 25% it's mana cost! It will also give you a lot of AP from it's passive. The 20% CDR is a god-send, CDR being a must-have on many champions. Additionally, at 750 mana it will become Seraph's Embrace which can give you a MASSIVE shield later on.
This is your main damage item, it will MASSIVELY boost your damage with Nether Blade and destroy towers with ease. Most Kassadin mains will agree that it truly turns you into the assassin you're meant to be. The mana and CDR mean that normally , if you've built this 3rd, you will be at 30% CDR.
The hourglass that is considered, by most, a rather essential item on 90% of AP champions due to the active. The active, Stasis will help you survive in sticky situations while you wait for your Riftwalk to cool off, or for your team to catch up to you. The armor and the CDR will help you seal the deal on 40% CDR. Picking up Seeker's Armguard early in case you're against a very difficult AD match-up.
Your go-to magic penetration item. It give some AP but you're mostly buying this for the unique passive that grants 40% magic penetration.
This item will boost your ability power by a hell of a lot. It already offers 120 AP but it's unique passive is that it increases all your ability power by 40%! Making it an excellent last item buy if the enemy hasn't built magic resist.

Ability Sequence
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
This will be how you spend your Level Points on Kassadin in most cases with the exception of champions that have very spammy abilities or into Attack Damage match ups. Null sphere will usually be your poke ability and the magic shield will help you absorb damage for more favorable trades.
Ability Sequence
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
You should max Force Pulse first in the event that you're against an AD match up or against mages that have very spammy abilities. This skill does more damage earlier on compared to Null Sphere but it also has the unique cooldown of having to charge it with 6 spells that have been cast in your vicinity. This is his only for of wave clear pre-6.

This ability is part of the reason Kassadin is considered an anti-mage. He gains a magic shield after casting this ability for a brief 1.5 seconds. This skill can be used to block incoming magic damage during a trade while inflicting damage yourself. It also comes with a micro silence to disrupt channels and charged abilities. ( example : Shen's ultimate can be canceled.)
You'll often be using this to help you farm in lane and recover mana as each cast will give you some back depending on how much you're missing, against enemy champions, this can turn into a 40% missing mana recover. It is key to managing your high cost ultimate.
One of the most unique skills in the entire game due to having a double cooldown. It has a 5 second cooldown but, it also requires 6 spells to be cast around you. It has an incredible 90% slow when maxed! This skill is both useful for slowing enemies down to catch up , escape them, or to wave clear! It also goes right through walls like Yasuo's Wind wall.
This skill is what makes Kassadin iconic. The low cooldown , damaging flash. This is what makes him a terrifying champion to deal with as it not only offers him nearly unmatched mobility , but insane amounts of damage. It can stack up to 4 times going from 50 mana all the way up to 800 mana. Now this may seem like a lot, and trust me it is, but not without reason! At 800 mana this ability does 3 times it's original damage! Combine that with AP and maximum mana scaling, and you've got a tool that'll take your enemies by surprise. You can often R into Flash to cover a lot of distance and land that heavily stacked Riftwalk onto that annoying Lux! It'll also help you set up flanks and ganks from interesting positions that no one would normally anticipate, allowing you to jump in and out of combat.

And that's all I have for you! I hope you find this guide to be of some use, for any questions or any suggestions, please leave a comment below. Like the guide if you found it useful , dislike it if it was a waste of your time. Thank you for reading!
