Pros / Cons

And those are her Pros/Cons

-Noxious Blast,Miasma,Petryfing Gaze will allow you to catch up or escape anybody.

-Noxious Blast can be good scout tool,Cast it in brush that you suspect your enemy is,if you get your speed boost you will know enemy is inside.Same thing with stealthed enemies.

-At level 3 you can start using your endless combo:Miasma,Twin Fang,Noxious Blast,Twin Fang,Noxious Blast,Twin fang

-Your Deadly Cadnece should solve your mana problems at early game

-Sexy voices


-Easy target in teamfights

-Requests mana build late game

-Cant carry gamme

Creeping / Jungling

Addonitialy Cassiopeia can you jungle.
Start with Miasma followed by Twin fang.
Keep creeps iside Miasma and keep using Twin Fang.
Start with Elix of Fortitude and 3 health potions.
Dont drink Elix of Fortitude right away,first clear wolf,ghoul and 2 golem camps then recall and buy Elix of Brilliance.Go to Blue Buff drink bot elixes,make sure you have atleast 3 health potions and get your buff.
Start ganking around level 4.

I take typical caster runes:
-Magic Penatration marks(They are definitivy the best)

-Cooldown Reduction Seals(Far best as i can get from Seals)

-Flat Ability Power Glyphs and Quintessences

You noticed that i dont like "Per level" runes.Its becouse im trying to cover all items in early game so i get fed then nobody will care about late game.You gonna be just fine..

Taking magic penatration in offense.
Movement Speed,Cooldown reduction,More XP and gold,Improved flash in Utility.
I dont take anything in Defense becouse champion like Cassiopeia doesnt need anything defensive.

Guide Top


-Start up with Dorans Ring.Its definitivly best item for Ability power mage casters.

-Take Boots of Speed.Dont rush Soceress Shoes right away becouse Cassiopeia already has many chasedown and escape abilities.First take Atmphying Tome after boots then upgrade Boots in Socerres Boots.

-Atmyphing Tome followed by Blasting Wand and Giants belt upgrade to Ryalis Creystal Scepter.Ryalis Crystal scepter gonna make you less targeted becouse of your huge health.It will ensure you clean escape or catch up enemies.

-Zhryonas Hourglass is definitvly item that you need the most.Great ability power improvmance good armor(you dont really need armor)but generaly its Active:Passive,allways be ready to use it.

-Rabadon Deatchap-3 Words: HUGE ABILITY POWER.
Cassiopeia needs it

-Archangels Staff-Deadly Cadnece wont be doing all mana babysiting for you.Its time to do it on your own.Archangels staff is great item for it.Even though if you deside you need more survability grad Rod of Ages instead.

-Abystal Scepter:Gives me ability power,magic resistance and whats the best its lower enemies magic resistnace.As you may noticed i only have runes and Soceres Shoes for my Magic Penatration so grabing Abysall Scepter to reduce it is good.If your enemies are mostly AD grab Haunting Guise instead.But if your going well with both ad and ap casters/dps dudes grab Voids Staff.

-Nidalee-You are enable to catch her up in cougar form,and there arent many champions that can do it,remember it.Early harrasement while Deadly Cadnece is active will keep you full of mana and force her to use heal or die.Or farm her mana.You gonna have more mana then her if you force her becouse like i previously said you have your Deadly Cadnece.

Combo/Skill use/Skill Sequences

Flash/Petrfying Gaze:Petrfying gaze has small range so with flash she is enable to damage your opponet.
Miasma/NoxiousBlast:Your Miasma can lead your enemies,when enemies are leaded your Noxious Blast hit is more garanteed.
PetrfyingGaze/Miasma/Twin Fang:Stunning your enemies will keep them in miasma for about 2 second allowing you to place around 5 twin fangs.2seconds-1 twin fang pet 0.5. and one by leaving.

I take Miasma and Noxious Blast by level 2.At level 3 i have twin fang with other 2 spells i can keep poision active.Since level 3 i start building Twin Fang,Noxious Blast and taking Petrfying Gaze whenever availible.
