Threats & Synergies
Pre 6 you can all-in her whenever her charm is on CD. If you can bait it, she has no way of trading back. After level 6 you should be a bit more careful and stay behind minions when fighting. If you can land miasma on her she won't be able to dash or flash.
Take cleanse. He should never be able to 1v1 you when you have some items so he will just be looking to shove in the wave and roam. If he uses his W on the minion wave, walk up to him and hit him with your Q+E. After 6 you want to shove him in so he can't roam. Ward his side of the map so you know where he's going, and SPAM PING your teammates to back off.
This is a really good matchup for cassio. He has super high cooldowns early game so he can't take extended trades with you. If you ever hit noxious blast, just run him down with twin fangs. Back off when he's about to get the empowered Q as it deals a lot of damage. You need morello early to counter his healing.
Take cleanse for her bubble. Her abilities can be bodyblocked so if you shove her in, she can't do anything. She has no escape without flash so if she ever gets in range, or uses ult by mistake, run her down. Don't stay close to walls or fog of war.
Start corrupting potion, then harrass him as much as possible at level 1 with auto attacks and E as soon as he walks up to cs. Level 2 you need to respect his damage because he can easily burst you down with electrocute and passive proc. Keep your distance from this point and rush a seekers armguard for some tankiness. You will outscale in this matchup, so your focus should be to farm up and ward properly because he will roam the entire game. You can't waveclear as good as him once he gets tiamat, so ward the river and the middle of the lane so you can see in which direction he's headed after he shoved the wave. Getting a sweeper will show his shadow during his ultimate. He also can't jump over walls if you use your W:
One of Cassiopeia's main weaknesses is her short range. Xerath outranges her, so you should never have a chance of killing him if he positions well. You can still win this lane but it depends entirely on how good you are at predicting and dodging skillshots. His waveclear is also much better, so that makes it even harder for us as he can constantly shove in the wave after 1 complete item.
The issue with Ahri right now is her glacial augment path which is a huge problem for Cassiopeia because she's immobile and becomes really easy to run down afterwards. You want cleanse in this matchup both for her charm and the glacial augment slows. In the laning phase you should stay behind minions because the charm can be bodyblocked. Her Q deals true damage on the way back, so even if you get hit by the first part of it, try to dodge the last part. If you want to all-in her, try to get a stun on her WHILE she's trapped by your W because then she can't flash or ult away since it stops her coompletely.
She's mobile with CC, making it extremely hard to punish her. Watch out for when her passive is fully stacked and don't trade. Let her push the wave and try have it at YOUR SIDE OF THE LANE. Focus on farming and getting your core items. When trading, focus on dodging her E, and stay far away from your own minions so she doesn't use those to close the distance. You can cripple her mobility with W of course but you don't have to force risky plays because you outscale her hard in the lategame. Farm for your important items and outshine her in teamfights.

Welcome to my in depth Cassiopeia guide! I'm Yeager, a high elo midlaner in league of legends consistently reaching at least master tier on EUW every season since season 5 and challenger EUNE since season 9. I spend some of my free time creating high quality educational content to help you improve and become a better player.
Why should you play Cassiopeia? Cassiopeia is a mechnically difficult champion to pilot but also super rewarding once mastered. She is one of the absolute best scaling mages due to her insane DPS potential but also her passive that allows her to skip boots and buy 6 full offensive items. Her consistent damage and kiting potential makes her a solid pick into short ranged comps and especially tanks. Cassiopeia can also be played both mid and to plane, so if any of this sounds interesting, then this might be the champion for you.
+ Insane DPS
+ Huge outplay potential
+ 6-item lategame scaling
+ Very rewarding
Cassiopeia has been among the strongest midlaners since item changes was introduced to mages. She has insane DPS and full 6-item lategame scaling thanks to her passive. It's a champion that will reward you based on your skill level, so you can always be relevant with her even when she's out of meta. If you invest time into learning this champion, you will find yourself climbing the ranked ladder much faster.
- Mana hungry early game
- VERY High skillcap
- Short range
Cassiopeia's biggest weakness is her immobility and short range, making her weak into teamcomps with long-range abilities and strong disengage. She also has some manaproblems early on until you get Tear of the Goddess and Lost Chapter, so spamming abilities without managing your mana can cost you the entire laning phase. Due to her high skill-cap, it's a champion that can't be mastered from just 30 games, she needs lots of time and practice.
Flash Is a must-grab on mages like Cassiopeia because you're really squishy and require solid positioning. She does not have any built-in dash/jump, so 1 wrong move in teamfights can cost you a lot. Flash also enables the flash-ult combo.
Heal Used to be the standard summoner for most mages. It heals you and a nearby teammate, so if you are planning to skirmish a lot with your jungler, this is a viable option.
Ignite The go-to summoner for having kill pressure in lane. I use this one most of the time as it fits my super-aggressive playstyle, letting me grab some solokills in lane to scale faster, and take over the game.
Cleanse Underrated spell. If you are playing against a heavy CC mid + jungler, then you want Cleanse for sure. The benefit of having cleanse is the fact that you don't need to use a item slot on Quicksilver Sash, and can instead focus on buying your core items.
Exhaust This helps a lot against champions that rely on burst damage to finish you off. Champions this can be good into, are something like Fizz, Zed, Rengar, Talon, Ekko. Having Exhaust also makes your 1v1 splitpushing much stronger.
Barrier The more selfish summoner spell compared to Heal. It has lower CD and is a much safer pick against opponents with Ignite.
Ghost This used to be the best secondary summoner spell for Cassiopeia because it covered all her weaknesses. Due to the nerfs it's no longer a top-tier summoner, but it can still work in some situations.
|Serpentine Grace (Passive): Cassiopeia gains Movement Speed per level, but she cannot purchase Boots items.|
|Noxious Blast (Q): Cassiopeia blasts an area with Poison after a brief delay, granting her increased Movement Speed if she hits an enemy champion.|
|Miasma (W): Cassiopeia releases several clouds of poison, slowing, grounding, and lightly damaging enemies that pass through them. Grounded enemies cannot use Movement abilities.|
|Twing Fang (E): Cassiopeia lets loose an attack that deals increased damage to Poisoned targets and heals her for a percentage of the damage dealt. If the target dies from this attack, Cassiopeia regains Mana.|
|Petrifying Gaze (R): Cassiopeia releases a swirl of magical energy from her eyes, stunning any enemies in front of her that are facing her and slowing any others with their back turned.|
Twin Fang is maxed first as this is our bread and butter ability. It's our main source of damage and sustain, but it's also used to farm creeps since it refunds mana every time you last-hit a unit with it.
Noxious Blast is maxed second. This is where the great chase-potential comes in for Cassiopeia as it gives movement speed when you hit a champion. It's great for poking and kiting champions while shredding them fast with Twin Fang.
Petrifying Gaze is maxed third. Great ultimate that allows Cassiopeia to solocarry in teamfights. We put a point in this whenever we can for the lower cooldown and more base damage.
Miasma is maxed fourth and last. We only put a point in this ability early to have the slow + grounding effect so we can stop mobile targets and lock them in place.
In the early game you may have to play a bit more passive against some of the meta picks. Cassiopeia is really mana hungry until she gets tear, so you should avoid extended trades unless the target is within kill range. Use your Twin Fang to last-hit creeps and keep the wave at your side, so you can avoid getting ganked by the enemy jungler. Your main goal in the early game, is to have enough gold for Tear of the Goddess and a Control Ward. Once you have enough gold, you should shove in the wave OR freeze it, and base for your items.
When you have Tear of the Goddess you should always use Twin Fang to last-hit creeps so we can get some free mana and stacks. Since we now have a mana item, we can afford to play a bit more aggressive. If the enemy is overextended, you should go for trades with Noxious Blast + Twin Fang as she can shred people really fast, and often they won't be able to trade back because of her DPS, and the mobility she gets from Phase Rush.
Enemy junglers often camp Cassiopeia because she has no mobility. You can play aggressive if you have proper vision, but you still need to be aware of possible ganks. Always have a Control Ward in one side of the lane, and play around your vision.
At this point you should have at least Liandry's Anguish. Seraph's Embrace and Rylai's Crystal Scepter. If the enemy is not respecting you, you can play super aggressive and look for kills with Ignite. For a almost guaranteed hit, you should wait using Noxious Blast until the enemy midlaner stops to auto-attack a minion, and then run them down. There are not many midlaners that can match Cassiopeia's DPS at this stage of the game, so don't be scared of taking trades.
If the enemy midlaner is playing too passive, you should just shove in the wave fast and look for roams, or stealing away objectives/enemy jungle camps. Cassiopeia can kill dragons really fast with her insane DPS.
If you somehow end up on the losing team, don't lose focus because Cassiopeia outscales most midlaners lategame! Try stalling the game by clearing waves with your team until you are strong enough to carry. People always make mistakes when they are ahead because 1. They think it's won and lose focus and/or 2. They don't know how to close out the game. When they keep making mistakes and get punished for it, they will eventually get tilted, and that's when you can turn the game and make a comeback.
Late game is where Cassiopeia truly shines. For a mage, she has unmatched single-target DPS that will shred anyone who's within range. She also outscales most champions because she can build 6 full damage items! Late game for Cassiopeia is all about objectives and teamfights. As Cassiopeia you pretty much want to be constantly grouping with your team at this stage of the game. You can still go to other lanes to pick up big waves, but you should avoid splitpushing most of the time.
The way you play cassio in teamfights is the same as most other mages. You need to stay with the backline because you're incredibly squishy. Use your Miasma and Petrifying Gaze on the enemy frontline to lock them up, so they won't be able to use any mobility spells. The good thing about Cassiopeia is the fact that she shreds tanks REALLY FAST due to her insane DPS. Twin Fang.
Keep looking for opportunities where you can take big objectives like baron and elder drake . Cassiopeia can shred them really fast, so you must take advantage of this by constantly clearing out enemy wards and hovering around objectives.
- can be used to check bushes for targets. If you get movement speed when using it, it means a champion is there.
- The ability has a small day. Try predict where the opponent is moving before you use it.
- Enemies who are caught in this won't be able to use flash or other movement abilities. Use this to lock down high-mobile targets before you unleash your full combo.
- Has a minimum cast range, so it can't be used in melee range.
- You can W + flash
- The ability deals more damage on poisoned targets. This includes the poison from champions like Teemo, Twitch and Singed.
- Make sure to almost move around and not stand still while using Twin Fang. Doing this helps you dodge abilities and reposition better for your next Noxious Blast.
- The first basic trick on Cassiopeia is the Petrifying Gaze + Flash. It's the same as other ability + flash tricks where you ult in the direction you want, and then flash right after the cast time. This will catch a lot of people off-guard and can net you a lot of solokills.
What does it mean to freeze and how do i do it?
Freezing is a advanced technique that lets you deny your opponent exp and cs if done correctly. Freezing a lane means that you kite/tank the minions without letting your tower hit the creeps. You need to make sure the enemy minions always beat yours. After the enemy killed your entire wave, you let 2-3 of the enemy creeps live, and kite them until the next wave is here. When the next wave arrives, the wave will freeze right outside of your turret range.
By doing this, you are safe from jungle ganks, while your opponent takes a big risk everytime he overextends for a cs.
When to freeze the wave
You can Freeze the wave when you and the enemy are even or ahead, and it can be used to help you win back the lane after you screwed up and died. You can attempt to freeze the wave already from level 1, leaving your opponent vulnerable to jungle ganks or be within your kill range, if you are able to kill them. When you get a lead, and you can solokill an overextended enemy laner, that is exactly when you want to freeze the wave. You force the enemy midlaner to either be in your kill range, or miss a ton of cs and exp, putting them further behind.
Freezing a wave is a great way to snowball a lead, if you have no objectives to fight for, such as dragon, herald or towers.
