GUIDE STILL IN DEVELOPMENT
This is not the definitive version of this guide !
I'm still working on it. Here's a non-exhaustive list of things I still need to add/change:
- Add Build notes
- Add Items chapter
- Add Laning & Teamfighting chapters
- Complete Abilities chapter (with combos, tips, etc)
- Add match-ups
I'm getting closer ! Apart from match-ups (will come at last) I should be done in a few days. Be patient lads :-)

DESCRIPTION & TIPS
| PASSIVE: SERPENTINE GRACE |
![]() |
Cassiopeia gains 4 Movement Speed per level. She cannot purchase Boots items. |
| Q: NOXIOUS BLAST | |
RANGE: 750 | COST: 60/65/70/75/80 Mana | COOLDOWN: 3.5 |
| W: MIASMA | |
RANGE: 550-800 | COST: 70 Mana | COOLDOWN: 22/20/18/16/14 |
Miasma has a minimum cast range, and stops upon impacting terrain. |
| E: TWIN FANG | |
RANGE: 700 | COST: 40/50/60/70/80 Mana | COOLDOWN: 0.75 |
If Twin Fang kills its target, it refunds its mana cost. |
HEAL: 5 / 10 / 15 / 20 / 25 (+ 10% AP) |
| R: PETRIFYING GAZE | |
RANGE: 825 | COST: 100 Mana | COOLDOWN: 120/100/80 |
![]() |
Active: After a brief delay, Cassiopeia blasts enemies in a cone in the target direction, dealing magic damage to all enemies hit. |
MAGIC DAMAGE: 150 / 250 / 350 (+ 50% AP) |
Enemies facing Cassiopeia are stunned for 2 seconds, and all other affected enemies are instead slowed by 40% for the same duration. |
RECOMMENDED SUMMONER SPELLS
![]() |
FLASH: Mandatory. Cassiopeia can only rely on her movement speed if she needs to dodge/escape, meaning Flash is a MUST-HAVE on her. |
![]() |
IGNITE: This spell allows Cassiopeia to win trades in the very early game. If you pick it, I advise that you start with a ![]() ![]() ![]() ![]() ![]() |
![]() |
EXHAUST: A nice option if you're facing an assassin, or any champion with high burst damage. I would totally recommend this spell over ignite against champions like ![]() ![]() It will also help later into the game, e.g. if you know you're losing a trade. |
PICKABLE SUMMONER SPELLS
![]() |
BARRIER: Even though I'd rather pick exhaust if I feel like needing a defensive summoner spell, Barrier is still a logical choice on a squishy champion like Cassiopeia. |
![]() |
CLEANSE: Situational. Pick it only if needed, e.g. if you're facing a heavy CC composition, or if this gives you a clear advantage against a certain champion, such as ![]() ![]() ![]() |
BAD SUMMONER SPELLS
![]() |
GHOST: Flash is way more efficient, without a single doubt. Plus, you already have a lot of movement speed on Cassiopeia, you really don't need more, especially when it's so temporary. |
![]() |
HEAL: Totally MEH. Heal is meant for duo lanes. Barrier or Exhaust both do a way better job when used correctly, and again, you don't need another movement speed buff on Cassiopeia ! |
![]() |
SMITE: You're not a jungler. |
#1: STANDARD AP RUNE PAGE

Here is the most common rune page for AP champions. It gives you powerful stats that will help you during your laning phase, but also throughout the game. The AP Quints and Magic Pen. Marks make your damage output a bit bigger during the early game, while the Armor Seals and Magic Res. Glyphs will reduce the damage you take, whatever damage type your lane opponent deals; overall, these defensive stats will also make you a bit less vulnerable during the whole game ! |

512 IP x 3 = 1536 IP total

#2: AGAINST AD LANER

Here is a specific page for when you face an AD champion. The only thing here that differs from the standard rune page are the Glyphs. Indeed, as this page is meant to help surviving against physical damage, we don't need magic resist at all. Instead, I choose to go for 6 CDR Glyphs and 3 AP Glyphs. There are plently of other viable choices as for replacing magic resist, if you'd rather go scaling AP, or mana regen, or whatever, it's all up to you ! These here are just my favourites. |

#3: AGAINST AP LANER

Here is a specific page for when you face an AP champion. The only thing here that differs from the standard rune page are the Seals. Indeed, as this page is meant to help surviving against magic damage, we don't need armor at all. Instead, I choose to go for Flat Health Seals. Overall this is a totally common AP vs AP rune page. Trust me, these 72 Health can make a big difference in your early trades, especially if you face an assassin, such as ![]() ![]() |

#4: POPULAR CASSIOPEIA RUNE PAGE

Here is a long-time popular rune page specific to Cassiopeia. This page is focused on SCALING statistics. Thing is, before patch 5.9, Cassiopeia's previous passive ![]() This is the main reason why this rune page was (and still is) recommended on many guides. My opinion is, Cassiopeia still scales with game length, but nowadays I would advise to rather go for specific vs AD/AP pages, or even the standard one, as scaling statistics and the lack of flat resistances make you extremely vulnerable during your laning phase. |

#5: MY RUNE PAGE (CDR = OP!)

Here is my favourite rune page for Cassiopeia. I advise that you use this page if you know you're going to have an easy match-up. Indeed, if you happen to face a counter like ![]() ![]() That being said, the 10% CDR will allow you to make a better use of ![]() ![]() |

So there are two Keystone Masteries that work well on Cassiopeia:
Thunderlord's Decree
VS
Deathfire Touch
.
This is mostly a matter of personal preference, though there is actually a main reason why you would pick one over the other: EARLY GAME FOCUS VS LATE-GAME FOCUS.

Choose this mastery page if you want to focus on killing your lane opponent.
A few explanations:

This is mostly a matter of personal preference, though there is actually a main reason why you would pick one over the other: EARLY GAME FOCUS VS LATE-GAME FOCUS.
EARLY GAME FOCUS: THUNDERLORD'S DECREE

Choose this mastery page if you want to focus on killing your lane opponent.
A few explanations:
- Since our goal here is to kill our opponent, we're going to use
Assassin
and
Oppressor
for more early game damage.
-
Savagery
will ensure that we don't miss last-hits with
Twin Fang, thus avoiding to waste some precious Mana.
- The 5% CDR from
Intelligence
will allow us to easilier cast 4
Twin Fang over our Q duration. More on that in the CDR on Cassiopeia section.

- The 5% CDR from


Specific Tips:
- At level 1, cast a few
Noxious Blast to lower a bit your opponent's health, eventually forcing him to use a potion. Do this when he comes to last hit to ensure it's not going to miss.
Don't cast more than 3 of them, or you'll miss mana to use many Es after you level up.
- At level 2, try to hit your Q only when you know you'll be in range to follow up with
Twin Fang. Then cast only two of them, as you want to proc
Thunderlord's Decree
but also save your precious mana.
- At level 3, spend a second point into
Twin Fang. If you executed the previous steps correctly, your opponent's health should be low enough for you to kill him with the following combo:

Don't cast more than 3 of them, or you'll miss mana to use many Es after you level up.
- At level 2, try to hit your Q only when you know you'll be in range to follow up with


- At level 3, spend a second point into

Q + Ignite + E + E + E + E (+ Q).
LATE GAME FOCUS: DEATHFIRE TOUCH

Choose this mastery page if you want to focus on increasing the strength of your damage-over-time.
A few explanations:
- Since we're aiming at late game with this mastery page, we want to take
Bounty Hunter
and
Wanderer
, as they are more efficient in the long run.
-
Secret Stash
is really helpful during the laning phase, especially considering we mainly want to passively farm and stack our
Tear of the Goddess.
-
Deathfire Touch
has reduced effectiveness when applied by AoE or DoT damage, but if you cast
Twin Fang after
Noxious Blast, your opponent will suffer the DoT from both your Q and Deathfire, at the same time !

-



Specific Tips:
- Focus on farming. Don't bother killing your opponent, this is not what you're aiming for with this mastery page; keep your spells to trade him back if he engages on you.
- In order to make your laning phase even safer, I advise that you start with a
Corrupting Potion for more sustain; this will also scale well with
Secret Stash
.
- Don't pick
Ignite if using this mastery page, again your goal is to farm ! Instead, you can grab
Teleport to make sure you don't miss CS, or any other situational summoner spell (e.g.
Exhaust if you face an assassin.)
- In order to make your laning phase even safer, I advise that you start with a


- Don't pick
