Welcome to my Kassadin guide.
I'm quite the veteran player with Kassadin. I think I've got 600-700 Kassadin games on my belt, but who's counting (I lost track after ~500 when Riot removed the stats on normal games, haha).
I'm confident that I've tried out most playstyles and found the best one. The build is kinda cookie-cutter, but that's not necessarily a bad thing.
I hope you enjoy the read.

My whole rune set is basically very standard on AP casters.

Greater Mark of Insight
There's not really any other options for a magic damage caster.

Greater Seal of Clarity
You need a little extra mana-reg during most stages of the game. I go with scaling runes over flat because you don't really need that much mana-reg before you get your ult and the level after that (7) is when scaling get better than flat.
Greater Glyph of Force
Makes you hit a little bit stronger. I run scaling over flat AP because they cross over so early. It's at about lvl5 that most casters get dangerous from leveling up their spells and that's where scaling AP runes pass flat runes.

Greater Quintessence of Potency
Nothing else can really compare to AP quints on most casters.

Flat MR runes are great if you're in a lane match up you're supposed to lose (Sion and Morgana among others). AP/lvl is overall the better choice since you'll obviously aim to not get counterpicked.

Summoner Spells

Kassadin is already a crazy teleporting void monster, why would he want Flash? Because:
  • He's very vulnerable to early ganks.
  • There are times enemies can teleport after him.
  • There are times where you jump into a bigger mess than you thought it'd be(GTFO button ftw).

Great spell to have sometimes, but I generally prefer Flash over Cleanse because early ganks can really screw you over (Cleanse is rather useless for escaping most early ganks).

Great spell for beginners, to make the lane easier. Quick heals and item purchases are lovely early on.

Very useful because it will make snowballing much easier. Kassadin often needs that little extra omph to get the job done.

You can shut down casters easily and your nuke is often too much for squishies to handle, but sometimes Exhaust helps with getting those pesky tanky DPS off you or your teammates.

Ability Sequence
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Null Sphere is your only reliable source of damage and should of course be maxed first.

Force Pulse after that because it's your second most reliable source of damage.

And Nether Blade is not very useful in most match ups so leave that for last.

Taking a point in W at level 4 is sometimes a viable choice. It's primarily useful when you're against champions with good sustain or enemies who simply can eat your harass and live.

Sometimes I get the last rank of Force Pulse over rank 2 of Riftwalk, but that's only if I'm in a position where my nuke is more important than my mobility. You'll generally want to rank Riftwalk whenever you can though.

(abilities)Your kit and how to use it

Weapon Mastery

(actually named Void Stone, but Matt is too lazy to update it <3)
Makes you strong against casters. Sadly the attack speed bonus is almost useless, but the damage blocking part is pretty strong.

Tips and tricks:
  • In some rare cases you can tank a spell to receive higher DPS while hitting someone/something. Don't bother with that when you're new to Kassadin though.

Null Sphere

This is the spell that enables you to win your lane. High damage+silence makes a lot of casters lose if they trade with you. With Riftwalk you can force them to trade (or even silence before they can cast anything).

Tips and tricks:
  • It has a silence, herp, derp. There's really not much else to keep in mind about this spell.

Nether Blade

Pretty bad spell. It's rare that you get a good opportunity to attack in melee safely and the extra mana is abysmal.

Tips and tricks:

Force Pulse

The only spell in the game that charges from spells used in the vicinity.

Tips and tricks:
  • (Yes, I'm "saying" it again. It's that important) Charge your Force Pulse with Nether Blade outside of big fights. It can make a big difference sometimes. I've even gotten kills by using Nether Blade to gain the last Force Pulse stack in a critical moment.


Riftwalk, Riftwalk, Riftwalk, Riftwalk, Riftwalk.

This is really the spell that makes Kassadin Kassadin. Huge mana costs when used repeatedly, but it would be way too strong without that.

Tips and tricks:
  • There's one thing I really can't stress enough. That Riftwalk is NOT a primary source of damage. While there are moments it can be used for extra damage those moments are rare. Riftwalk is for transportation and last resort damage. Like when Null Sphere and Force Pulse are on cooldown and an enemy is about to escape. Never use it on an enemy to initiate. The problem with using Riftwalk for damage is that you open yourself up for damage. Should a squishy caster give the enemy an opportunity to kill him? I don't think so... A good Kassadin attacks the enemy but never lets them attack him. (well, that's the goal at least, haha)

  • Deal damage then Riftwalk away when you have the option to choose. That is the safest way to get your damage off. Another safe way is to jump on or close to ONE enemy and silence+slow him/her. Just make sure that it really is just 1 enemy. It usually isn't all that safe if the enemy has a disable though.

General tips

  • Blue buff is a great asset. It gives 7.5% of your max mana as bonus MP5 and 15%/20%/25% CDR depending on your level. It enables you to freely harass the enemy in your lane. Ask your jungler if he can give it to you when you need it (after you're lvl6 ofc).

  • Never sacrifice yourself for others if you have a killing spree going (Kassadin are prone to those, haha). That's like donating gold to the enemy team.

  • Try to keep close to walls whenever you can. It makes escaping easier.

  • Ambushing enemies through walls is great, but it's important to be aware of how many enemies there are at the other side. Riftwalking into several enemies is bad, so very bad for your health.

  • Use Zhonya's Hourglass whenever you end up in a bad situation. I'm gonna name some moments it will help.
    • When you've got a DOT or a delayed spell (like Ace in the Hole, Requiem and Time Bomb) on you that will kill you. Make sure that you're a safe distance away from enemy champions though.
    • When you're about to be hit by a disable in a tricky situation. ( Rocket Grab and Cryptic Gaze among others)
    • When you have Riftwalk on cooldown and is about to be hit by a ton of damage.

Possible builds

Kind of a cookie-cutter AP carry build. Not much to say about it other than the fact that it gives plenty of damage and a little durability.

Guide Top

Starting Items

Boots of Speed
Mobility is very important against 90% of the enemies you'll face in mid, especially since you're melee.


3 Health Potions
These enable you to win trades with most enemy casters in mid and if there's something Kassadin needs; it is to win his trades.

Doran's Ring or Sapphire Crystal+2pots are not bad or anything, but they're just too heavily outshined by boots+pot start.

Guide Top

Core Items

Rabadon's Deathcap
THE damage item for casters. Is your job to deal magic damage? Get it.

Void Staff
Everyone builds MR (sooner or later) if there's a caster like Kassadin in the match.

Rod of Ages
In my opinion the best item to solve Kassadin's mana problems. A little bulkiness is also very good since there'll be less chance of being nuked when exposing yourself.

Sorcerer's Shoes
Not much to say. You'll want these 95% of the time.

Guide Top

Why not TotG

Because Tear of the Goddess takes way too long before it's useful. With Rod of Ages you get AP, HP and mana right away and great lane sustain.
Buying tear makes your earlygame noticeably weaker and makes it harder to snowball even it it's a little stronger in lategame.

Back when I used defense for HP-reg ( Strength of Spirit ) I just needed mana and mana reg to sustain myself, but after the nerf Rod of Ages is by far the best way to start off in my opinion.

I don't advise against getting it later in the game, but getting it early is just not worth it.

Guide Top

Preferred Items

These are items that I personally prefer. If these don't suit your needs just look among the Other Viable Items.

Zhonya's Hourglass
A bunch of AP and a great active. This also balances out your damage mitigation at about ~55% for both magic and physical damage because of your passive.

banshee's Veil
The "shield" is perfect for your periodically intensive presence. It will discourage casters from spending spells on you while up.

Guide Top

Other Viable Items

Archangel's Staff
Good, but often the less attractive choice. The biggest problem is the time it takes before it's useful. Only buy this in lategame.

Mercury's Treads
Void Staff reduces Sorcerer's Shoes' effectiveness by 34% ( Archaic Knowledge ) and they're not quite worth it anymore in comparison. That is why they are a great replacement if the game lasts very long. Even if that is very rare, it's just something to keep in mind just in case.

Lich Bane
Not an item I use much, but it has it's uses.

Quicksilver Sash
Removes ALL debuffs. Just like the old Cleanse. Oh how I miss it.
Great item if you're scared of disables, debuffs and magic damage.

Rylai's Crystal Scepter
Not optimal, but not bad either.

Ionian Boots of Lucidity
Not bad, but you'll be the owner of blue buff most of the time, so the CDR isn't always that useful. Elixir or Brilliance is a more attractive source of CDR.

Will of the Ancients
Not quite worth getting early since you'll be rushing Rod of Ages. I don't really think sustain matters that much to Kassadin in lategame, but it's still viable if you like sustain. It's a great item for new players.

Guide Top

Laning Phase

Kassadin is an anti caster. He's best matched against frail casters without sustain. Since he's a caster he should always be in a solo lane. Preferably mid to make his earlygame easier with the short distance to the tower. At top he's very vulnerable to mobile enemies and ganks. You'll flat out lose your lane against most tanky champions with sustain. Well, most champions with sustain in general.

Try to stay mostly defensive and focus on lasthitting and not getting hurt below lvl5. Don't be afraid of using Null Sphere to lasthit minions, but make sure you don't use too much mana on that.
When you reach lvl3 you should begin to weaken your lane opposition. Harass the target as much as you can, but of course try not taking any unnecessary damage or overextending. When (and if) your opponent gets low enough that you think you can kill them with your combo and you have your ult; you should try to kill them. Keep good track of your mana and always measure your damage to make sure you can get the kill before going in! Make an assumption while taking their magic resist into consideration. If the enemy never gives you an opportunity for a kill just focus on keeping him away from gold and maybe even exp. That's much better than going for a kill when you're unsure whether you'll get it or not.
Push the minions against the enemy tower if they recall or die, then recall yourself. Just make sure you aren't taking any chances. After that you can go gank or get golem if you think you can do it without losing a tower.

As always; I'd like to express how important it is to only lasthit when you aren't pushing (or pushing back a big enemy wave). You're simply taking unnecessary risks by pushing into enemy territory when you aren't gunning for their tower. Especially important against junglers. You should also only lasthit when you're trying to keep the enemy away from lasthits.

Map-awareness is extra important because of how quickly Kassadin can traverse the map with Riftwalk. If you see the enemy jungler invading or even your jungler meeting the enemy jungler you can 100% get there before the enemy mid laner. That often results in kills, so be aware of what is happening whenever you can.

Guide Top


Stay on the outskirts. Don't join the fray. Jump around killing people while not giving your enemies a chance to kill you. You operate outside the battle, assassinate key targets and never expose yourself to more danger than you can handle. Do not use melee attacks unless you've got a death wish. You can of course use them in the aftermath though.

Hold off using Riftwalk until you really need to go over something or need to get to or away from a point quickly. Using it too much will quickly starve your mana pool and make you useless.
One option is to walk to up your target(s), silence, slow and then Riftwalk away if the area poses a threat. Only use Riftwalk offensively (teleporting into battle, instead of out) when you're sure that it's safe.

Try to silence key disablers, supporters or damage dealers at decisive moments. Make sure they haven't already used their spells. Though it's hard being picky when you can't take much damage. Just don't use spells on bulky targets when you have the choice.
Silencing anyone when they're about to save or disable someone can make a big difference in the outcome of any fight.
