Hello fellow readers. My summoner name is Nightcrawl and I am currently Diamond 2 on the EUW server.

Cassiopeia was my most played champion in S2 and S3 and is currently my 2nd most played in S4.

This guide is really short and made to teach the basics of Cassiopeia.

Offensive choices :

- Rabadon's Deathcap : More AP = More damage
- Void Staff : Maximum penetration
- Zhonya's Hourglass : Nice AP / Allows to initiate more safely / Counter AD
- Sorcerer's Shoes : More penetration / Get early for lane dominance
- Liandry's Torment : Even more penetration / Tank shredding / Some early health

Defensive choices :

- Abyssal Scepter : Gives a nice amount of MR
- Banshee's Veil : Prevents lethal CC late game ( e.g. Rocket Grab / Unstoppable Force / Assault and Battery
- Guardian Angel : If you get focussed a lot / Nice in combination with Chronoshift / Omen of Death
- Spirit Visage : Boosts your healing through Will of the Ancients ( only in combination with WotA of course ) and gives some nice MR

Utility choices :

- Athene's Unholy Grail : For some really needed mana regen and magic resist
- Rylai's Crystal Scepter : Really nice choice for overall slowing and kiting (skip Zhonya's Hourglass for this item if you can
- Will of the Ancients : Spellvamp on Cassio works great / Skip Liandry's Torment for this item
- Seraph's Embrace : When playing vs AD champions build Tear of the Goddess over Chalice of Harmony since you don't need the MR

General laning :

-Always try to poke as much as possible and use twing fang as much as you can

-Keep your enemies on their toes by pushing them into their turret while constantly harassing

-Always keep both sides warded

-You can cast your Petrifying Gaze and then Flash to land it easier

Level 1 :

-Poke as much as possible with autoattacks and Noxious Blast

-If you land 2 or 3 in a row you can Ignite the enemy which makes them blow Flash a lot of the time

Level 2-5 :

-Hit Noxious Blast and follow up with autoattacks and Twin Fang

Level 6+ :

-Always try to land nice ultimates on your foe and look for as many all-ins as possible

Teamfights :

-Stay in the back and put down a lot of AoE's with Noxious Blast and Miasma

-If you see the opportunity to hit a group of enemies with Petrifying Gaze go for it

-Spam Twin Fang on squishy carry champions

-Don't forget to use Zhonya's Hourglass
