Hello everyone! My League of Legends Alias is SmashedHippo and I'm here bringing you my first build/guide for Cassiopeia. Before I go into any detail, I'd like to note that this guide is subjective to my play style. It can however, be modified to satisfy one's preferences in game.
This is what some of the terms used in this guide mean:
AoE = Area of Effect
DoT = Damage Over Time
Ult = Ultimate
Mpen = Magic Penetration
AP = Ability Power
Mp5 = Mana per 5 seconds
HP = Hit Points or Health
Lv = Level
CDR = Cooldown Reduction
Pros/Cons (Why play Cassiopeia?)
- Great AoE in teamfights (Ult, Noxious Blast)
- Awesome ability to focus a target (Twin Fang)
- AoE slow
- One of the best DoT Mages in the game
- Insane damage on your Ult + Stun/Slow
- Focused in team fights
- Not durable at all
- Not an easy champion to learn to play
Nothing really that notable about the Masteries chosen. The most important things to know are that the utility tree gives you CDR, which is important for Cass, and the offense tree provides Mpen which is described why it's important in the "Runes" section. I also invest 3 points into
because it gives your mana pool a little more "wiggle room" for harassment.
The item sequence for Cassiopeia consists of an early Tear of the Goddess, to charge and build into an Arch Angels Staff later in the game. Next, build a Rabadon's Deathcap, followed by a Rod of Ages for the midgame. Whether you choose a Deathcap or Rod of Ages first is completely situational. For instance, if you feel that you are being focused in mid game fights, and need a little more survivability, go for a RoA. If you are dominating the enemy team and want to make a speedy conclusion to the game, a Deathcap would accomplish that. A lot of people also think that by getting a RoA, they are losing ability power they could've had from a Deathcap. I've done the math, and with a fully charged RoA and the passive from your Arch Angels Staff, it gives you 101.75 ability power! I choose not to rush a Rylai's Crystal Scepter because its passive only slows by 15% for all of her abilities, excluding twin fang. Her speed boost from noxious blast already gives you a good chasing ability as well, so I don't feel that a Crystal Scepter in the early game is necessary quite yet because it costs a lot for what you get out of it.
For my skill sequence, I max Twin Fang first because it's your main source of damage output. It is important not to neglect getting 1 point in Miasma before level 6 because it can deter melee champions from chasing you, and it is an easier way of poisoning the enemy for your Twin Fang if for whatever reason, you can't land a Noxious Blast. Note that Noxious Blast costs less mana than Twin Fang and it poisons your opponent. Unless they don't know how Cassiopeia plays, harassing with Noxious Blast will deter them from engaging you because they know they'll get 2 Twin Fangs in the face. It is also more mana efficient to keep your passive stacks with Noxious Blast because it costs the least mana and you'll have 50% the mana cost on your ultimate and your Twin Fangs - the abilities that cost the most mana.
I hope I have helped you improve your Cassiopeia play! Please leave your feedback in the comment section below (I do read it) and rate my guide :D! I will continue to update and improve upon myself, Thanks for reading!
