Cassiopeia is one of my FAVORITE champions of all time. She requires understanding the flow of her enemies, also extremely quick combo smashing. In the right hands, Cassiopeia can literally obliterate just about anyone.

Pros
- Cassiopeia is super spammy and fun.
- Around 2.9k hp by late game, and with rylais + spell vamp, almost impossible to kill me .
- Extremely easy to deny others, just pop your Q everywhere.
- Great AP carry, can EASILY carry a team even if you've fed the whole game.
- Game changing AoE stun.

Cons
- Hardly any cons for Cass, but she does require some skill to use.
- Annoying when your poison stops and your E has a 3 sec cd.
- Mainly good for a single target dps.
- Ult has a decent range, but sometimes it can glitch and piss you off.

Core Build:

RoA for extra survivability and AP. Really makes you able to survive that damn Veigar's ult during team fights.
Sorcerer's Shoes for much needed magic pen.
Rylai's for a boosted slow. DON'T LET THEM GET AWAY!! Spam yo fangs gurl!
WoTA, I've found, works extremely well with her AoE and her Twin Fang. It returns massive amounts of HP :D

Situational Items

- AMAZING boost to your ap. Makes you hit that much harder.
- Just for those teams who like to stack MR.

- If your DoT from your Q isn't enough, ignite is sure to do the job.

- Why would you not take this OP skill? Use it to initiate with your stun, get out of sticky situations.

Other summoner spells that can work include

- Needa get that huge mob? TELEPORT <3
- Good for chasing down those *****es and running away.
- Meh. You could get this, but I really prefer the others.

Thanks for reading!!!
