Threat Champion Notes

Zed This is contrary to the usual beliefs, really easy matchup in general. Things to mind: Ganks, high gank pressure. W shifting = Don't save your W, use it off cooldown if zed uses his shadow, so he can't ever close the gap on you. What makes this matchup easy, and how to abuse = Zed is really linear champion. You know when he is looking for a window to all-in you, and you can abuse this. If you see he's lookin for the opportunity, just throw W ahead of him, and follow up with ult, if he doesn't instantly back away. Now you can dps him, he can't ult, or shadow dash. IF ULTED, quicktip= Throw W, and flash in it. He cannot swap around, and you can ult him immeatedly, since he will be trying to DPS you during his ult. Run Teleport Optionally (Ignite, Barrier, lastly Exhaust)

Introduction

Hey!



This is my first guide, and I haven't had too much time on my hands. This is still something I've wanted to share for a long time, so go easy one me, and give me tips to improve :). First off, a little bit about me. I have been playing league since season 3 started. I have picked up Cassiopeia just now in season 6, after the healthy changes to her kit regarding to the ability to spam E, and still remain the movement command at the same time. My main account was placed in Diamond 3 at the end of the season 5, and I started practicing Cassio in that elo. After a few twenty games, I decided to start from the bottom on a smurf, and see how far I can get on a one-trick pony based account. I got 8 accounts at the moment.


The Blue Cobra (Eune,Masters, Cassio onetrick)


The Biue Cobra (Euw, D2, Cassio onetrick)


Corp Toofyes (Euw, D5)


Corp blue cobra (Euw, D4, Cassio onetrick)


Smurf Blue Cobra (Euw, D5)


Blue Cobra V2 (Euw, D5, Cassio onetrick)


Byroedw (Euw, D5, Cassio onetrick)


I Singed In Jung (Euw, -, Singed onetrick)


The reason I got this many, is mostly playing with friends Many of them have decayed over time, usually from D4- D3 to Plat.




For my surprise, Cassiopeia proved to be really strong in the lower elos especially. It took me a bit over a month, to climb from silver 2 to Diamond 1, on 'The blue cobra'(Eune) in 150 games (+random other champs I occasionally had to play). I promise you, if you master this champion, you can climb a whole division just by dominating the middle lane. And the best part is, you will fall in love with this champion, and enjoy playing her even after you have reached your first set of goals.



I WANT TO ADDRESS, THAT THIS GUIDE IS A WORK IN PROCESS, AND SHALL BE UPDATED. All the basic knowledge you need to know is here, just the reasoning will updated further on. In this state the guide provides only my opinion how to build her, the more detailed one for beginners, with comboing, laning, takes more time, which I try to scrap up as soon as I can. All of the feedback is more than WELCOME, So please comment :) ALSO, I'm sorry this guide has not yet been updated fully, I am really occupied with my thesis at the moment in the univeristy. Thanks for your patience!







As most of us know, Cassiopeia underwent huge changes in patch 5.9. They literally BUTCHERED her. Now, in 5.10, they finally blew some life into her again.


I finally think riot has done enough, and made her a dominant force again, to petrify anyone who dares to go eye to eye with her. She is finally as good as she was before, with a little more complexity.



Buffs


Noxious Blast, The Range buff is really nice, it's quite an unseen buff. Don't forget the high mana cost though, it's still 60- mana at rank 1.


Miasma, Also buffed nicely, the range is really high now, and the minimum range is JUST ABOUT enough, (Could be still a bit lower though)


Twin Fang THANK GOD, they finally reduced the cooldown to 0.75, which is enough for now, can barely even notice the difference anymore.

Items

Cassiopeia is somewhat item dependant, since you can consider her as an AP version of AD carry. The most beautiful part of Cassio is the fact, that you can go so many ways with your item builds, and the priority of items. I Try to explain in this section the thought process I use to determine what items to buy, and when.



Against AD Assassins


This is the lane, I consider hardest to play as Cassiopeia. Champions like and do huge burst damage to you, leaving little time to react. The sole purpose of Cassiopeia is to dish out constant damage. The thing I NEVER DO, is build Zhonya's Hourglass. You're purpose is to kite, as for the purpose of zhonyas is to deliver your burst, and go untargetable after. The thing you SHOULD DO, is rush HEALTH. I Find myself usually going for Rod of Ages and rushing Rylai's Crystal Scepter after. At this point you should have at least 700 raw HP, to counter the burst. From here on out, you got several paths you can go to. The fact that you can build so many things, means you have to think about your situation when you get at these breaking points.



Against Control Mages



This is the most comfortable matchup for cassiopeia, since nobody does control as well as cassio. Champions like , , are some of the easiest to lane against as Cassiopeia. This doesn't mean that the build is going to be always the same against these control mages. I take usually three paths, which is decided by the lane pressure:



[*] Farm lane / You pace the aggression


If my lane opponent can't harass me off the lane, but I simply can't go all in on him to press my advantage, OR it isn't worth anymore, the lane turns into FARM LANE.


In this situation, if I deduce that the laning phase is going to be long, I buy Tear of the Goddess on my first back, and then rush Rod of Ages Perfect example is generally .


[*] You are getting pressured / Enemy paces the aggression


By the first back, try to scavenge enough money for Catalyst of Aeons. This will counteract the poke, and pressure a little bit. Afterwards proceed again with Tear of the Goddess Straight for Rod of Ages after and then rush Abyssal Scepter.


[*] Pressing your advantage,


On Cassio, pressing your advantage come from little things. The build usually stays the same, because you are always looking to scale. The little change comes from the build paths, E.x When building Rod of Ages, build Blasting Wand before finishing Catalyst of Aeons




Quick Note, AP ASSASSINS



Tough one, the core build Tear of the Goddess, Rod of Ages and Rylai's Crystal Scepter stays the same, but in this case you might find yourself rushing Negatron Cloak Straight after Tear of the Goddess. This is really situational, BUT NEVER rush Abyssal Scepter. After Negatron Cloak proceed with rod of the ages. Then complete Abyssal Scepter, and proceed to Rylai's Crystal Scepter




Finish with optional items



[*] When ahead AND enemy team is low on resistances


Archangel's Staff OR Rabadon's Deathcap


[*] When even or behind OR heavy resistances


Void Staff






With this build CDR comes from your runes, FORGET ABOUT MORELLO. :)

Summoner spells

You can optionally swap , to



, this is the one I use most after teleport. Usually against or



, I usually use this only against , every little damage matters in those short trades. If you manage to land your ult while she uses W, you have 2 rotations of E. You need the



, the one that comes to my mind, is and . I Also use against these ones though.

Runes

More detailed reasoning incoming later on.



Shortly, with takin the CDR in our rune page, we allow ourself to build the optimal way for cassiopeia. None of the CDR items fits Cassio too well, so this way we get the best of both worlds.

Masteries

Simply, lane, dominance. As Cassiopeia you want to dominate the laning phase, and be the one in control of the trades. This is mainly the reason I like running Thunderlord's Decree . I have been experimenting on Deathfire Touch , and I have to admit, this is viable too in certain situations.

I would consider Deathfire Touch better option in lanes, where you are expecting longer trades, and not to be bursted out quickly. Also if the enemy team is heavy on tank stats, Deathfire Touch helps out your lategame.

If the lane is explosive, like or I would take usually thunderlords.

With Deathfire Touch I suggest you try out as secondary summoner spell, which gives you a bit of the lane dominance that Deathfire Touch lacks. is still more than fine, though. Executive call depending on the matchup and their team.

Working on more detailed explanations!



**Thought process on HOW to choose between Thunderlord's Decree OR Deathfire Touch



This is optional, and depends what you play against, and what you are playing with. I have experimented alot with both, and both of them are strong in certain situations.

#1 Deathfire Touch (1)Farm lane, (2)you can't abuse the enemy hard, but you also (3)don't need the additional pressure to keep your enemy in line (E.x Orianna), OR Tanky enemy team +3, or +2 heavy tanks, OR Your team lacks the damage later on, hence you need all the AOE dmg you can get.



#2 Thunderlord's Decree , if you face an enemy, that you HAVE to pressure hard, e.x. Leblanc, Viktor, Fizz, (Usually bursty champions) or YOU CAN abuse hard (Ryze, kennen, zed).


Firstly look at the #1 option, if it matches to DFT, take it, even if second part would indicate Thunderlords.

Statistics

My performance and stats. A tiny bit of validation for my way of playing Cassiopeia, especially at the moment, when the guide lacks a bit of reasoning.
