Threats & Synergies
Easy lane to poke down with q and can chase her down when you hit 6
Careful of her burst during lane, as it is both AD and AP. Attempt to interrupt her roams as the lane is oppressive in your favor.
Pretty simple lane, poke with q and eat her combos with your shield if necessary. When you hit 6 remember to save your q for when she channels her ult so you can end it.
Annie q is very telegraphed for you to eat it with your magic shield. Easy to outmaneuver her burst and go for a kill
Slightly different from many other champions. Careful he doesn't get any huge roams off, as your waveclear doesn't come close to his. Also, be wary of the fact that his w range is longer than your q.
Against a good azir player, you must respect his poke from relative safety. Try let him push and wait until 6. You can riftwalk past his wall and his soldiers.
Easy to dodge skillshots and easy to shield spells.
Cassiopeia is one of the few AP champs that can actually threaten kassadin in lane, especially with the current Abyssal mask build. Her E will break your shield and then she can proceed to chase you down with autos and e. Be very careful during laning phase and avoid any long trades.
You can negate half his damage with your shields, but respect his early damage. Try to whittle him down so he has to either back or risk dying to your q e w combo.
Easily telegraphed spells, but her pesky shield won't allow you to do much during laning phase.
Skill matchup. If you let the ekko poke you down too much, even through your magic shield, he can dive you and get an early lead.
Uncommon but still dangerous, especially if they go ad. Avoid fighting in lane if they have fervor and focus on last hitting. You will be able to kill him later when you have more mobility.
Skill matchup favoring kassadin. If a fizz wastes his e on your q, all in right away. You still get your magic shield if he dodges it, but your cds are shorter. When 6, keep a finger on your ult in case of the stray fish.
Very difficult to kill throughout the game. Do not attempt to trade at any point of the laning phase unless your'e sure he doesn't have any cds.
The occasional gragas mid can be very dangerous for kassadin as gragas has much more burst early on in the game. Stay back and farm until you won't get oneshot.
Eat his ability damage with your q and poke him out of lane. If he stays too far to poke, wait patiently until 6 to fight him. Make sure to juke out any of his empowered abilities or his stun.
Give up you can't win and fights. Hug the turret super hard until you get some help.
Just like cass, avoid any long trades that allows them to abuse their dps. Poke him down until you can oneshot him.
As long as you spellshield her q, you win lane. Bait kat into one of her daggers by standing near, and q a minion right before she jumps on it so you can get a free e w combo.
Kayle is a strange champion. Laning with her is easy and you can destroy her by just poking her down. However, later in the game her ult prevents your from oneshotting her, and if she gets enough items she can turn on you. Be very careful whenever there's a kayle.
The advent of lethality kayn mid is not a welcome sight for kassadin. Try your best to dodge his w in lane and just poke whenever you can.
Skill matchup. If you can spellshield her q and dodge her e, you will win trades hard.
She can't do enough damage to break your shield. Only be wary of her amazing gank setup.
Lucian mid abusers should die to be perfectly honest. Just like jayce, hug your turret and call for help.
Very easily telegraphed ability damage. Make sure to q a minion to avoid damage if Lux is too far away.
Similar to lissandra, you win trades pretty simply, but you must be careful of their ults during a gank setup. Always ward your sides.
Time your q with her q w combo and you should win lane to an extent. Killing ori in lane is tough because of her lane control and shields.
Super simple lane, runs out of mana quickly and doesnt trade well when one of his q is nullified by your own.
Your q and syndra q have similar range, so use your q whenever you see her about to use her own. Laning is easy as long as you avoid any ganks.
Talon will first blood you if you don't hug your turret. As with other AD assassins, rush a zonyas.
Very easy lane to block damage and poke hard. Might be recommended to bring cleanse instead of tp because of twisted fate's guaranteed stuns are brutal.
Extremely easy lane. All skillshots means that dodging and eating them with your spellshield is simple. If he isn't dead by 6, just bait out a knockup and go all in.
His deceptive tankiness with his shields and his burst make him tough to kill unless you get the jump on him, or if you managed to poke him down earlier in the game.
Nearly impossible to kill at any point of the game, though he is easy to run away from. Try to get a gank from your jungler to take vlad down.
Immobile champions=Easy picking for kassadin
Skill matchup favoring yasuo. Poke his windwall away, then go for trades. You should never be in range for you to use your w unless he dashes into you himself.
A good zed is one of kassadin's hardest matchups, though not impossible. To beat zed is just to dodge his abilities, which may be difficult the better the zed is.
Eat his poke with your shield and poke him whenever possible. When 6, don't waste your ult without a second thought because he can knock you away with his w, or ult you.
Play as aggressive as possible in the early laning phase, to either bait out his mana or zone him from cs. When 6, take great care to ult past his wall. You can build zhonyas if you feel like you're in danger of getting one shot.
FlashFlash is the best summoner spell, self-explanatory.
GhostTeleport is quite useful to Kassadin, for either getting back to lane or teleporting bot lane for a gank.
IgniteOnly take ignite if you know you can bully the enemy laner hard and possibly get an early kill to help snowball the game.
Summon AeryAfter playing KASSAWINNN during the preseason, it has become clear that Summon Aery is indeed the best rune to take, to survive the harsh mid lane matchups.
Manaflow BandKassadin struggles to farm against hard AD matchups, having to expend most of his mana on just clearing the waves. Manaflow Band helps so much, giving you a chance to get into the mid game.
TranscendenceMore CDR always helps, especially because most Kassadin builds only reach up to 30% cdr in favor of more damage.
Gathering StormI take this rune over Scorch for the sole reason that Kassadin has a bad early game, and Scorch won't make him win lane either. I'd rather have the long scaling rune for the huge late game damages.
Presence of MindATTENTION ATTENTION THIS IS THE BEST RUNE ON KASSADIN!!!! GIVES YOU MANA BACK WHEN YOU GET A KILL OR ASSIST. YOUR ULT BECOMES BASICALLY FREE SO YOU CAN JUST JUMP EVERYWHERE AND KILL EVERYONE
Coup de GraceGreat rune for any assassin that needs to finish off a kill with bonus execution damage.
Void Stone, you can avoid a large portion of enemy magic damage. Again, against AD matchups, Null Sphere takes lower priority to your E Force Pulse.
Nether Blade's active is an auto-attack reset, giving you deceptively high damage in the early game.
Force Pulse is a strange ability, being the only ability in the game that requires charges to even cast. Kassadin gains a charge whenever any ability is used in his vicinity. At 6 charges, he gains access to Force Pulse, which deals damage in the cone in front him, slowing all hit. This ability is great for catching someone out and for chasing. Also, against AD matchups it is the first ability you max.
Kassadin's real source of utility and mobility. Kassadin will teleport into the cursor, dealing damage to all hit. Each consecutive Riftwalk in a window of time costs double the mana and does bonus damage, stacking up to 4 times. Riftwalk's cooldown gets shorter as you level it up, until it is only a couple seconds long, meaning you have some of the most mobility in the entire game. Using Riftwalk, Kassadin can both escape most ganks, along with roaming to any lane pretty simply.
Best item to pair along with The Dark Seal. Give Kassadin some much needed sustain.
Take this is as your second item if you aren't behind. The Sheen proc along with your Nether Blade add to your full combo greatly.
CDR is quite important on Kassadin. Pick these up for quicker ult cds, and to cover up for the lack of Insight .
A very simple Kassadin combo late into the game is to r+e into the enemy team, then proceed to Zhonya's Hourglass. This item is very important for survivability and the bit of armor, ap, and cdr.
This item is really nice for the long fights because of the mana regen items, althought it means you will have your powerspike a bit later. It's a good buy if you want to go into later game.
Build this if you are ahead in lane by a good amount and have the right amount of money. This prevents your enemy laner from getting back into the game.
This might be the weirdest item to some, but it works like a charm. ONLY build this item if they have heavy AD damage, but still are squishy enough to oneshot.
Similar to the Cassiopeia build with Abyssal Mask, this gives Kassadin tankiness and not bad damage, as it makes the opponent take more magic damage. Only build this against extremely strong AP.
Good for a bit of AP, CDR, and magic resist, along with the useful spellshield against heavy cc
These are situational boots for if you are either geting cced for too long or if the other team has a lot of auto attack reliant champions.
For the first wave, you want to let the enemy push, as they are usually ranged champions. Make sure you hit level 2 before you let the minions hit your own turret. Nether Blade's passive and active allows you to farm quite efficiently underneath your own tower. Alternate between farming and harassing the enemy. If you bring Ignite you should play a bit more aggressively. Another tip is to always use your Nether Blade active whenever you can, as it restores your mana when it hits a target.
Final tip, while walking and roaming around, make sure to use your Nether Blade to stack up your Force Pulse charges. Riftwalk is Kassadin's bread and butter. When you hit 6 in lane, you gain a massive increase to your own kill pressure. Be sure to play much more aggressively in lane once you have your ult, using your full damage combo to land some huge poke.
