Introduction



First of all, this is a build and build explanation, this will not teach you how to play Cassiopeia as a champion, it will simply teach you how and why to build her in this way. Secondly, you should not follow this guide or any other guide to the letter, use your brain and forgo those Sorcerer's Shoes in favour of Mercury's Treads if you're up against a Veigar.

Offensive Tree
Summoner's Wrath 5 AP when ignite is on cooldown, more AP!
Brute Force Easier last hitting
Butcher Even easier last hitting
Sorcery Cooldown reduction and to gain access to tier 3
Arcane Knowledge A great damage boost
Havoc A small damage boost and to gain access to tier 4
Blast A noticeable late game AP boost
Archmage A small Rabadon's Deathcap?
Executioner Possibly the best mastery in the game for anyone hoping to do damage, amazing on Cassiopeia


Utility Tree
Summoner's Insight Flash more often
Expanded Mind To gain access to tier 2
Swiftness Not really useful unless you're maxing it, can be moved into Improved Recall .
Meditation More mana regen, more Noxious Blast casts
Runic Affinity Longer blue buff, amazing

Summoner Spells

Great for chasing, escaping, ganking, stealing, absolutely mandatory on Cassiopeia.


Fantastic damage over time with a healing reduction, useful all game due to the fact it inflicts true damage.

Can replace Ignite for split pushing, teleporting to wards for ganks, saving somebody from a gank or even getting back to lane quickly if you are being poked back to base.

The standard Cassiopeia skilling order, allows for maximum lane harassment early game with great mid game burst power.

Ability Sequence - Kill Lane

Ability Sequence

Far weaker harassment than the standard lane but with stupidly strong early game bursts, if you're the kind of person who likes to get first blood, second blood, third blood and more in your lane, this will suit you much better. However, if you fall behind while using this skilling order you will have your *** kicked and then some in lane.


Guide Top

Item Build - Standard Lane


  • : More mana, more Noxious Blast casts, more harassment
  • : Incredible lane sustain for what it costs, combined with Chalice of Harmony, you should be able to out-harass your opponent with ease
  • : Brings your damage closer to true damage
  • : AP, health and a great slow on twin fang, what's not to love? Oh, and it stacks with the slow from Petrifying Gaze!
  • : Crazy AP boost
  • : Allows you to q-w some minions to save going back to base to heal, works on nearby allies too! Great vs all comps especially poke comps
  • : Adds AP, magic resist and cooldown reduction to your Chalice of Harmony, I get this last as Cassiopeia isn't heavily reliant on cooldown reduction


Guide Top

Item Build - Kill Lane


  • : Incredibly cost efficient and provides early game late domination
  • : Brings your damage closer to true damage
  • : Needs no explanation, late game this will be taking off close to 50% of someones health not counting magic resistance not to mention the 90 AP it gives you
  • : Crazy AP boost
  • : AP, health and a great slow on twin fang, what's not to love? Oh, and it stacks with your ultimate!
  • : Allows you to q-w some minions to save going back to base to heal, works on nearby allies too! Great vs all comps especially poke comps
