Hello and welcome to my guide for Cassiopeia. The Serpent's Embrace is a quite underestimated champion. I experienced that not a lot people play her and I really wonder about that as she is a strong AP Carry.

As Cassiopeia is really fun for me I tried to play her in different ways and as I watched somebody jungling with her I just had to try that myself. It's really fascinating. As there is no Jungling Guide for Cassiopeia so far I want to share my way of playing Cassiopeia with you.
I won't tell you that jungling is the only way to play her. I also won't tell you that you will own every match just with following this guide. I wrote this guide to help YOU. But it's totally up to what you make out of that.

I hope you enjoy. ;)

Who is Cassiopeia?

(+3,2 / per level)
(+75 / per level)
(+50 / per level)
Move Speed
(+0 / per level)
(+4 / per level)
Spell Block
(+0 / per level)
Health Regen
(+0.1 / per level)
Mana Regen
(+0.15 / per level)

Always answer this question to yourself before you play any champion. You need to understand Cassiopeia's role to play her effectively. Cassiopeia is a AP Carry that deals a lot of damage with her spells.
She deals decent AoE damage and can stun the entire team with her ultimate. Her overall good damage makes her a real threat.
Anyway, Cassiopeia is not an easy champion. Playing her is challenging. But if you master her you maybe got one of the strongest mages in game.
Cassiopeia is not the strongest nuker. She can nuke squishies but she can't deal as much damage in a few seconds as Veigar (for example). But in contrast to usual nuke mages Cassiopeia's does not decreases when they used their nuke. Just have a look at Veigar. He is not toally useless when he used his ultimate. But his damage - in comparison - is much smaller and he has to wait for his cooldowns to be gone. Cassiopeia can deal a lot damage the whole team fight through what makes her - in my opinion - to a threat that can't be countered that easy. You can avoid Malzahar's or Veigar's nuke pretty easy. But this does not work against Cassiopeia as she is spamming her abilities. You might be able to dodge or block one. But that's neglectable.

Why should I jungle?

A jungler should be an essential part of your team. A jungler grants you a solo lane that can level up faster and farm more money than in a duo lane. The jungler as well can level up pretty fast - early to mid game - and earn money without getting annoyed.
The great advantage a jungler is granting to your team is that he is able to help any lane that needs help. It's not rare that your team is facing enemies that dominate a lane. Some good ganks by your jungler can help to reach a level and gold advantage so your team mates will be able to hold their lane more easily. A jungler also can hold a lane when a team mate wants to recall. So your towers are save from being pushed.
In addition to that it is much easier to get kills in your lane when you have a jungler.

Why should I jungle with Cassiopeia?
It is important to have a balanced team composition. A pretty common tactic is getting an AP Carry for the mid lane, an AD Carry + Support for the bottom lane, somebody for a solo top lane and a jungler.
A perfect team composition would include 2 AP, 2 AD and 1 Support champion. So you should choose a solo top and jungle champion that grants you this composition. If you got an AP based solo top champion just like Mordekaiser, Rumble or Galio you want an AD based jungler like Nocturne or Olaf.
But if you already have an AD based champion for the top lane you should get a AP based jungler like Amumu, Maokai, Fiddlesticks.... or Cassiopeia.

Cassiopeia is one of the rare AP based junglers. And in comparison to other AP based junglers Cassiopeia's damage is one of the highest. So if you already got a tank and a mid lane Cassiopeia is a great choice to complete your team composition with another AP champion.

  • fast jungler
  • dangerous ganker
  • strong AP champion from mid to late game
  • good amount of CC

  • needs blue buff to jungle fast
  • squishy
  • pretty easy to counter jungle early game
  • not easy to play

    I wouldn't write this guide if jungling with Cassiopeia doesn't work. Here is a typical statistic I'm used to have. I totally dominated the lanes what gave us an early win. I already said Cassiopeia is a fast jungler and dangerous ganker, especially after lvl 6. Once I noticed enemies began to buy wards I got an Oracle's Elixir to destroy them. As my enemies were very CC heavy I decided to buy Mercury's Treads.

Greater Mark of Magic Penetration

Greater Seal of Evasion

Greater Glyph of Scaling Mana Regeneration

Greater Quintessence of Health

Runes are something personal. These are the runes I prefer. But this does not mean that you need exactly these.

I was thinking a lot about Masteries and I finally decided to go for 9-9-21. It is giving me a great damage boost from offensive masteries, granting some defense for saver jungling and a lot utility.
Let's have a closer look at that.


  • Resistance (1/3) is not the most important mastery but, well, it is giving some magic resistance.
  • Hardiness (3/3) is granting more armor what is making jungling easier.
  • Evasion (4/4) is a must-have when using dodge seals. If you dont have these seals go for Defensive Mastery or Harden Skin instead.
  • Nimbleness (1/1) ... 10% more movement speed when dodging an attack. This tool is amazing. Together with your decent dodge chance this will save your life more than once.

  • Good Hands (3/3) is a much better choice than Perseverence as you will most likely die at least 2-3 times. 10% is a lot here.
  • Perseverence (1/3) has to be taken.
  • Awareness (4/4) is essential for a jungler as you want to level up as fast as possible.
  • Meditation (2/3] is giving you some more mana regeneration what is important on Cassiopeia.
  • Utility Mastery (2/2) helps you to keep your blue buff as long as possible. I already said that this is essential when you want to jungle with her.

Okay, this is not the only way to build Masteries for Jungle Cassiopeia. If you plan on building her on your own these are masteries that are also viable for her:

No other viable masteries in here. Havoc may be decent but it isn't worth the points you need to invest for it.

If you plan on building Cassiopeia more defensively you may want to go for 0-21-9.
Go for Veteran's Scars , Ardor and Tenacity . They are boosting your defense as well as your Ability Power.

9-0-21 is a common way to build a mage. You can also build Cassiopeia this way. But remember that jungling won't be that save then.
Quickness is making Cassiopeia faster. It's pretty useful as she isn't that fast anyway.
Intelligence and Presence of the Master are very viable for any mage.
When using the corresponding Summoner Spells you might want to get Haste or Blink of an Eye .

Summoner Spells

Rule No. 1: You need Smite!

Every jungler needs smite. It is making jungling faster and saver what will help you to level up faster. Being able to gank earlier and more often is essential for a jungler. Even it late game it's still useful as it will help to save Baron, Dragon and Buffs.
Because you are using Plentiful Bounty you will get gold whenever using Smite. This means that you should use it whenever possible as long as you don't plan on doing Baron/Dragon/Buffs!
Thanks to Ciderhelm for this video. It actually shows one great aspect of Smite. It is great for stealing and saving buffs. If you are able to counter the enemy jungler this way your team got a great advantage.
It is also showing how important wards are. I will mention that aspect later on.

Both Summoner Spells are great escape or harass tools. That means they can either save your life when you get focussed or ganked or help to kill an enemy that is running away. It is up to you what Summoner Spell you use for that. On the one hand Flash is great because it helps to jump over walls or e.g. avoid Veigar's stun area. On the other hand Flash is pretty useless if you jump over a wall and all enemies just do the same. Ghost may be a good counter for this reason.

  • Deadly Cadence helps Cassiopeia to spam her abilities. Anyway, in early game this won't solve your mana problems at all.
  • Noxious Blast is not easy to aim but deals some serious damage. When you hit your enemy you are able to use Twin Fang twice before the poison ends. It is essential to hit with it when ganking. Otherwise it will be hard to follow an escaping enemy. It is also a great tool to escape yourself.
  • Miasma deals more damage the longer your enemies stay in it. So you should use it when the team fight already started to make sure you deal as much damage as possible. When enemies are running away try to predict where they are going to slow them. It is also great to save allies or yourself when getting ganked.
  • Petrifying Gaze is an awesome ultimate. Actually there is not a lot to tell about. Just try to stun as many enemies as possible.

Skilling order:

I level Noxious Blast followed by Twin Fang. It allows you to spam Twin Fang till all jungle creeps are dead. I just put one point in Miasma and level it last as it deals minor damage in comparison to the other abilities and I just need to slow early game. Leveling Noxious Blast and Twin Fang together grants me a most effective damage output as I will not always be able to spam Twin Fang on enemy champions when ganking a lane.

Items | How to build Cassiopeia

We start with a Cloth Armor and 5 Health Potions. We need the armor to jungle saver by getting less damage from creeps. Health Potions help to gain life points when you get damage.

This is our core build. There is no particular order for getting these items. 2 Doran's Rings give us some essential life points, a decent amount of Ability Power and enough mana regeneration you need when you don't have blue buff. Boots of Speed are increasing your movement speed. This is important to stay mobile. Hextech Revolver is giving you some Spell Vamp. After you get this item you don't have to buy any Health Potions.

These are your mid game items. Sorcerer's Shoes are granting you enough movement speed and some decent magic penetration.
If you are facing a very CC heavy team you might want to get Mercury's Treads instead. Against a AD heavy team Ninja Tabi could be a decent choice in combination with your dodge runes and masteries.
Rylai's Crystal Scepter will make it impossible for your enemies to escape. As you are able to spam Twin Fang it means a constant slow. When you are in a hurry you also just need to use Noxious Blast to get a speed buff AND a slow on your enemies. The additional life points are giving you enough defense for mid game as well.

You are on the way to late game. Congratulations. This little item will give you a great boost to your ability power. If you are having some trouble you might want to get a defensive item (listed below) before that.
Many matches will come to an end at this time. But if you are having a long game there are some decent options for additional items.

Optional Items:

The following items are optional. Buy any of them corresponding to the actual match.

Feel free to upgrade your Hextech Revolver any time. It's just 900g.

Zhonya's Hourglass is a great choice if you want to get even more AP without neglecting your defense. The armor is great against physical damage and the active effect will help save your life more than once.

Abyssal Scepter is giving you a decent amount of magic resistance. The Ability Power boost is nice and the additional magic penetration will increase your damage a lot.

Archangel's Staff is a good choice for Cassiopeia as she is a skill spammer. Anyway I recommend getting Tear of the Goddess as soon as possible. You might want to skip at least one Doran's Ring for this reason.

Who cares about the magic resistance you get about it? Lich Bane provides a huge damage buff. You will trigger its affect a lot and there is always time for a auto attack between two Twin Fangs.

I don't really like Rod of Ages for Cassiopeia. But if you feel like you need more HP without neglecting your offense this could help. It will also help against mana problems.

Do you want to buff your nuke ability together with some CDR? Just get Deathfire Grasp.

Void Staff is a great choice when your enemy is stacking magic resistance.

As it is a snowball item only get Mejai's Soulstealer when you are doing really well.

You want to get Banshee's Veil against a team with a lot magical damage and/or very annoying spells.

Against certain enemies with certain abilities (Malzahar's ultimate, Warwick's ultimate, ...) Quicksilver Sash could be useful.

I know that his item usually is reserved for tanks. But if you feel like you are having trouble against AD champions Randuin's Omen is an awesome item.

Jungle Route:

1.) You start at the Blue Buff. Ask for gank protection and a good pull. Cassiopeia is doing a bit hard with killing the golem at level 1. You will need a Health Potion in here.

2.) After that head towards the Wolves. Keep enemies poisened and spam Twin Fang.

3.) Now it's time to get the Wraiths.

4.) Finish the small Golems and recall.

5.) Get some health potions and Boots of Speed when needed.

6.) Get red buff.

7.) You are now level 4. Look for some opportunities to ganks and jungle after that.

Jungling Basics
  • Use Poison and spam Twin Fang till creeps are dead.
  • Save mana for ganks when you don't have blue buff.
  • Help your lanes when needed. Ask if you should hold a lane to let somebody recall.
  • Gank lanes as often as possible. Use Noxious Blast and Miasma to close the gap between you and your victim. Spam Twin Fang till your enemy is dead. Try to come from behind so your enemy can't escape easily. For this reason you should tell your team mates not to push lanes. Use your ultimate when needed.
  • Use wards to gain map awareness.
  • Give red buff to someone who really can need it.
  • Buy and use Health Potions till you got your Hextech Revolver.

The Importance of Warding

Warding is not your main job. Anyway, helping your support with buying additional wards gives a huge advantage to your team.

What kinds of wards do exist?

sight ward
  • sight wards (75g) should be bought usually.
  • Vision Wards (125g) are more expensive but can be used against champions with stealth ( Evelynn Twitch Shaco,...) or to destroy enemies's wards or Teemo's mushrooms. As enemies can't see these wards (as long as they don't have one) it can surprise stealth champions more than a Oracle's Elixir could do.

Why is warding important?
Wards are giving you map awareness.

And what is map awareness good for?
If you can see what the enemy is doing you can counter his actions.
  • If you know where your enemy is he can't gank.
  • Wards allow to gank enemies when you recognize you are in a superior situation.
  • Wards can defend buffs because you'll see when enemies are to kill the corresponding creep.
  • Wards let you know when the enemy jungler is doing red/blue buff, Dragon or Baron. Wards are a great tool to steal them with Smite and maybe get a kill.
  • To sum that up: Wards help to make game changing decisions. You need to spend money for wards. But actually you will get this money back when you get a kill due to a better map awareness.

Where should I place wards?

Wards should be placed to get as much information as possible. For this reason you should place wards at crossings to check more ways with only 1 ward.
Here is a good example for that. This wards gives vision to 4 paths and blue buff. At least one enemy will most likely pass through the ward's vision range.

The next image is also a good location for wards. You can check the river and baron with it. I usually choose a Vision Ward for this because probably the enemies will have their own ward here. Vision Ward can uncover it so my team is able to destroy them. The same is for dragon. If your team plans to kill either dragon or baron it is important to know if the enemy can see what you are doing.

This image is showing some of the most common places for wards. Credits for it go to Panglot.

When wards are so important, can I do something against the enemy's wards?
Yes. Vision Wards and Oracle's Elixir can give you vision on enemy's wards. Even when the enemies don't have stealth champions Oracle's Elixir is very viable. Check for common ward locations to destroy them.

If you want to learn more about wards I can highly recommend Panglot's
