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. ;)

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.

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.

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.





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 .

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.

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.

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 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.

Thanks to Xenasis for his images. If you want to know more about jungling I can highly recommend his guide Jungling 101 - What You Need To Know

Actually, you already know a lot about Cassiopeia now. And there is not much left.

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?



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.


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.
