Champion Background Strategy Skins & Trivia

Skill usage

  • Stacking up Aspect of the Serpent.png Aspect of the Serpent is paramount for CassiopeiaSquare.png Cassiopeia.
    • Landing Noxious Blast.png Noxious Blast on enemy champions helps her stack faster. Miasma.png Miasma is a great tool to try to engage/disengage safely. Poisoning multiple enemy champions do not give extra stacks but it does do damage to both so keep that in mind.
    • Note that even if you do not spam Noxious Blast.png Noxious Blast on enemy champions, Aspect of the Serpent.png Aspect of the Serpent will still stack every 6 seconds. Know when you hit your powerspikes to play aggressively with this.
    • 3-6 Twin Fang.png Twin Fangs can be cast for each Noxious Blast.png Noxious Blast without putting Twin Fang.png Twin Fang on full cooldown. The number depends on how close you are to your target as twin fang has a travel time and a 0.5 second cd on reset. Be aggressive with this in lane, even when a trade goes poorly. Getting stacks of Aspect of the Serpent.png Aspect of the Serpent quickly is paramount.
  • Each benchmark of Aspect of the Serpent.png Aspect of the Serpent is a massive power spike for CassiopeiaSquare.png Cassiopeia.
    • At 100 stacks, CassiopeiaSquare.png Cassiopeia gains a very small AP boost and significant health sustain which, along with the mana sustain from Twin Fang.png Twin Fang, allows her to stay in lane very well just last hitting with Twin Fang.png Twin Fang. As well, this allows CassiopeiaSquare.png Cassiopeia to trade and duel very well.
    • At 250 stacks, CassiopeiaSquare.png Cassiopeia gains a decent AP boost and can have her poisons up constantly. The CDR also means failing to Twin Fang.png Twin Fang a poisoned target is less punishing and keeping targets poisoned is easier.
    • At 500 stacks, generally hit around 20-35 minutes on Summoner's Rift, CassiopeiaSquare.png Cassiopeia gains a massive AP boost, equal to and stacking with Rabadon&#039;s Deathcap item.png Rabadon's Deathcap's passive.
  • CassiopeiaSquare.png Cassiopeia is a great harasser in all stages of the game. All three of her basic abilities, especially Noxious Blast.png Noxious Blast, can be used constantly in lane to zone, capable of dealing damage over time at a safe distance. Twin Fang.png Twin Fang provides the bulk of her damage at any stage of the game though.
  • CassiopeiaSquare.png Cassiopeia must play fairly safely until she hits late game; however harassing is very important for gaining stacks and farming is a very large part of her gameplay.
  • Noxious Blast.png Noxious Blast has a slight delay; lead your enemy when targeting with Noxious Blast.png Noxious Blast to ensure the hit, or use it on them when they will have to stand still to last-hit.
  • Using Noxious Blast.png Noxious Blast in the brush does not reveal CassiopeiaSquare.png Cassiopeia, so when in the side lanes, use the brush to your advantage to harass with little to no retaliation from enemy minions.
  • Noxious Blast.png Noxious Blast can also be used to check brush, as it gives you a movement speed bonus (and a buff icon) if an enemy is hit. If you cast it in a brush, and notice the buff icon, you know that an enemy is there.
  • Noxious Blast.png Noxious Blast grants a significant speed boost, using this is crucial to juking skill shots and repositioning in fights.
  • When chasing/fleeing, be sure to use your Noxious Blast.png Noxious Blast on an enemy champion to speed yourself up, and Miasma.png Miasma to slow them down.
  • Since Miasma.png Miasma grants vision over the area affected, it can be used to check brush.
  • Twin Fang.png Twin Fang is the main source of Cassiopeia's mana and health sustain.
    • It is crucial to last hit with Twin Fang.png Twin Fang to sustain your mana. Using Twin Fang.png Twin Fang repeatedly on a high health target, like tanks or Dragon or Baron, will drain your mana.
  • Twin Fang.png Twin Fang becomes extremely powerful if the target is poisoned, allowing you to deal out large amounts of damage with its low conditional cooldown.
    • It is very highly recommended to smart cast Twin Fang.png Twin Fang, as it will make it much easier to land the maximum amount of Twin Fang.png Twin Fang allowed by the duration of your poison effects.
    • Due to Twin Fang.png Twin Fang having the potential to be constantly refreshed, don't be afraid to target durable melee champions if necessary. Unlike many other mages that rely on burst damage, CassiopeiaSquare.png Cassiopeia and her Twin Fang.png Twin Fang can realistically cut through tough enemies with time, accuracy, and enough mana.
  • Twin Fang.png Twin Fang is reduced to a 0.5 seconds cooldown on cast, if the target is poisoned. However it doesn't matter who poisoned the target. So if you have a team-mate such as TeemoSquare.png Teemo or SingedSquare.png Singed who have a poison effect on their skills, use it in your favor.
  • Try to use Petrifying Gaze.png Petrifying Gaze offensively, and usually against more than one target. That said, it can also be used when being ganked to escape enemies.
    • It is, however, safest to use it when a team fight has happened. The enemy will be less likely to manage to turn around with their attention split amongst five champions - and more likely to all be facing you since that is largely required to fight your team.
  • Using Petrifying Gaze.png Petrifying Gaze followed by Miasma.png Miasma, Noxious Blast.png Noxious Blast and Twin Fang.png Twin Fang can turn most 1v1 fights and mid game turret dives in your favor.
  • You can cast Twin Fang.png Twin Fang and Petrifying Gaze.png Petrifying Gaze together for a surprise stun. This is really difficult to pull off.
  • Petrifying Gaze.png Petrifying Gaze also allows CassiopeiaSquare.png Cassiopeia to be a very strong anti-ganker. Simply casting it when your lane opponent and the enemy ganker are in range, then bursting down the weaker one with your combo can turn the 2v1 into a 1v1. This tactic is only effective when your Petrifying Gaze.png Petrifying Gaze stuns both targets.
  • Cassiopeia can proxy through the use of Noxious Blast and Miasma.

  • If you can predict when CassiopeiaSquare.png Cassiopeia will use Petrifying Gaze.png Petrifying Gaze such as at the beginning of a fight or at the end, you can avoid the 2 second stun.
  • CassiopeiaSquare.png Cassiopeia relies heavily on landing Petrifying Gaze.png Petrifying Gaze so that Miasma.png Miasma and Noxious Blast.png Noxious Blast are unavoidable.
  • When dueling her she will put  Miasma.png Miasma right on you, despite the constant damage from it the time needed to move out will let her spam Twin Fang.png Twin Fang to death. It's better to stay in the venom and outburst her.
  • CassiopeiaSquare.png Cassiopeia lacks a powerful instant nuke apart from Petrifying Gaze.png Petrifying Gaze, other mages who can nuke potently or disabling her like MalzaharSquare.png Malzahar or XerathSquare.png Xerath can effectively counter her mid-late game.
  • CassiopeiaSquare.png Cassiopeia has excellent range on Noxious Blast.png Noxious Blast and as her main harassing tool, outranging her is highly beneficial, mages like LuxSquare.png Lux and XerathSquare.png Xerath have a clear advantage.
    • These mages can also outburst her if done correctly.
  • CassiopeiaSquare.png Cassiopeia is a very powerful harasser. Noxious Blast.png Noxious Blast allows her to give her lane opponent a hard time, but also be wary for Miasma.png Miasma, as it can set you up for ganks, make landing Noxious Blast.png Noxious Blast or especially Twin Fang.png Twin Fang extremely easy, or zone you from minions very effectively. Buying Boots of Speed item.png Boots of Speed is a good and cheap way to limit her harassment.
  • CassiopeiaSquare.png Cassiopeia is extremely proficient at duels, having the most sustained damage of all mages (maybe only matched by VladimirSquare.png Vladimir). Therefore it is not recommended to engage her alone.
    • Champions who can outmatch her sustained damage but also survive the 2 second stun like VladimirSquare.png Vladimir, KayleSquare.png Kayle, EliseSquare.png Elise, or SwainSquare.png Swain can potentially duel and kill her.
  • Due to Noxious Blast.png Noxious Blast and Miasma.png Miasma, CassiopeiaSquare.png Cassiopeia is very powerful at kiting. If she gets Rylai&#039;s Crystal Scepter item.png Rylai's Crystal Scepter she will be almost impossible to reach if played correctly; do not engage her with a champion without strong gap closers or excellent ranges while also being able to withstand her damage in a 1v1 fight.
  • Avoiding her Noxious Blast.png Noxious Blast and Miasma.png Miasma is critical for your survival, as they deal heavy DoT, and being poisoned allows CassiopeiaSquare.png Cassiopeia to spam her Twin Fang.png Twin Fang on you.
