==Skill usage==
 
*Don't hesitate to spam your spells since {{ai|Deadly Cadence|Cassiopeia}} makes each additional cast cheaper. {{ai|Noxious Blast|Cassiopeia}} does not require a target, so maintaining your 5 stacks is easy with a decent-sized mana pool.
 
**Try to acquire 5 stacks of {{ai|Deadly Cadence|Cassiopeia}} before casting {{ai|Petrifying Gaze|Cassiopeia}} to lower its mana cost significantly.
 
*{{ci|Cassiopeia}} is a great [[harassment|harasser]] in all stages of the game. All three of her basic abilities, especially {{ai|Noxious Blast|Cassiopeia}}, can be used constantly in lane to zone, capable of dealing huge amounts of damage over time at a safe distance.
 
*{{ai|Noxious Blast|Cassiopeia}} has a slight delay; lead your enemy when targeting with {{ai|Noxious Blast|Cassiopeia}} to ensure the hit, or use it on them when they will have to stand still to last-hit.
 
*Using {{ai|Noxious Blast|Cassiopeia}} in the brush does not reveal {{ci|Cassiopeia}}, so when in the side lanes, use the brush to your advantage to harass with little to no retaliation from enemy minions.
 
*When chasing/fleeing, be sure to use your {{ai|Noxious Blast|Cassiopeia}} on an enemy champion to speed yourself up, and {{ai|Miasma|Cassiopeia}} to slow them down.
 
*Using {{ai|Miasma|Cassiopeia}} in the middle of the lane when enemy [[minions]] are coming will slow them and deal some damage giving advantage to your minions, this tactic is best used in pushes as intentionally pushing your lane during the laning phase opens yourself up to ganks.
 
*Since {{ai|Miasma|Cassiopeia}} grants vision over the area affected, it can be used to check brush.
 
*{{ai|Noxious Blast|Cassiopeia}} 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.
 
*{{ai|Twin Fang|Cassiopeia}} 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]] {{ai|Twin Fang|Cassiopeia}}, as it will make it much easier to land the maximum amount of {{ai|Twin Fang|Cassiopeia}} allowed by the duration of your poison effects.
 
**If the situation is favorable, try to cast {{Ability_icon|Twin Fang|Cassiopeia}} while directly on top of your target, as {{Ability_icon|Twin Fang|Cassiopeia}}'s reduced cooldown begins when the poisoned target is hit and not on spellcast.
 
**Due to {{ai|Twin Fang|Cassiopeia}} 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, {{ci|Cassiopeia}} and her {{ai|Twin Fang|Cassiopeia}} can realistically cut through tough enemies with time, accuracy, and enough mana.
 
*Try to use {{ai|Petrifying Gaze|Cassiopeia}} 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 teamfight 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 {{ai|Petrifying Gaze|Cassiopeia}} followed by {{ai|Miasma|Cassiopeia}}, {{ai|Noxious Blast|Cassiopeia}} and {{ai|Twin Fang|Cassiopeia}} can turn most 1v1 fights and mid game [[turret]] dives in your favor.
 
*{{ai|Petrifying Gaze|Cassiopeia}} also allows {{ci|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 the only effective when your {{ai|Petrifying Gaze|Cassiopeia}} stuns both targets.

{{StrategyHeader}}
==Build usage==
 
*Buying {{ii|Rylai's Crystal Scepter}} along with using {{ai|Twin Fang|Cassiopeia}} on a poisoned enemy gives her much more chasing potential, but don't forget hit enemy with {{ai|Noxious Blast|Cassiopeia}} from time-to-time to refresh the poison and the [[movement speed]] bonus for yourself.
 
**However, be aware that {{ai|Twin Fang|Cassiopeia}} only slows by 15% with a {{ii|Rylai's Crystal Scepter}}. This is intentional due to the mechanics having a potential to perma-slow an enemy, according to the developers.
 
**Also, {{ii|Rylai's Crystal Scepter}} plus {{ai|Miasma|Cassiopeia}} adds a very powerful slow to your enemies, giving {{ci|Cassiopeia|Cassiopeia}} more time to chase and land {{Ai|Twin Fang|Cassiopeia}} easily.
 
*{{ii|Void Staff}} works fine on {{ci|Cassiopeia}} if enough enemies have a high amount of magic resistance, as the potential low-cooldown and damage on {{ai|Twin Fang|Cassiopeia}} lets {{ci|Cassiopeia}} be less stringent in choosing targets compared to other mages.
 
*Buy [[spell vamp]] items like {{ii|Will of the Ancients}} to quickly restore health when hitting poisoned targets with {{ai|Twin Fang|Cassiopeia}}.
 
* A {{ii|Catalyst the Protector}} is a perfect early game item for {{ci|Cassiopeia}} allowing her to spam her spells more often with the extra [[mana]] and some [[health]] for survivability. This can then build offensively into an early {{ii|Rod of Ages}} or a more defensive {{ii|Banshee's Veil}}.
 
* Even if she doesn't need the mana, getting a {{ii|Tear of the Goddess}} and then upgrading it into an {{ii|Archangel's Staff}} will greatly increase {{ci|Cassiopeia|Cassiopeia's}} ability power.
 
** Starting the game with a {{ii|Meki Pendant}} to build {{ii|Tear of the Goddess}} afterwards will make spamming with {{ci|Cassiopeia}} even more affordable.
 
* Avoid building [[cooldown reduction]]. Because {{ai|Noxious Blast|Cassiopeia}}'s damage tick is constant and can only be reapplied, and using {{ai|Twin Fang|Cassiopeia}} on a poisoned enemy reduces the cooldown to 0.5 seconds (which cannot be further reduced by CDR), {{ci|Cassiopeia}} does not gain the significant benefit from CDR as other mages do.
 
** Therefore, {{ii|Rabadon's Deathcap}} will be the major purchase for when you want more damage as {{ci|Cassiopeia}}.

==Countering==
 
*If you can predict when {{ci|Cassiopeia}} will use {{ai|Petrifying Gaze|Cassiopeia}} such as at the beginning of a fight or at the end, you can avoid the 2 second stun.
 
**You will hear {{ci|Cassiopeia}} gasp before she activates {{ai|Petrifying Gaze|Cassiopeia}} (.65 casting time), so you have a brief moment to react to {{ci|Cassiopeia}}.
 
*{{Character_icon|Cassiopeia}} is a very powerful harasser. {{ai|Noxious Blast|Casseopeia}} allows her to give her lane opponnent a hard time, but also be wary for {{ai|Miasma|Casseopeia}}, as it can set you up for ganks, make landing {{ai|Noxious Blast|Casseopeia}} or especially {{ai|Twin Fang|Casseopeia}} extremely easy, or zone you from minions very effectively. Buying {{ii|Boots of Speed}} is a good and cheap way to limit her harassment.
 
*{{ci|Cassiopeia}} is extremely proficient at 1v1 fights, having the most sustained damage of all mages. Therefore it is not recommended to engage her alone. Since {{ci|Cassiopeia}} has very high [[ability power]] scalings, she remains a constant threat to AD carries late game, since if she lands her ultimate, she can easily kill an AD carry without resistances within the 2 second stun {{ai|Petrifying Gaze|Casseopeia}} provides her.
 
*Due to {{ai|Noxious Blast|Casseopeia}} and {{ai|Miasma|Casseopeia}}, {{ci|Cassiopeia}} is very powerful at kiting. If she gets {{ii|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 while also being able to withstand her damage in a 1v1 fight.
 
*Avoiding her {{ai|Noxious Blast|Cassiopeia}} and {{ai|Miasma|Cassiopeia}} is critical for your survival, as they deal heavy DoT, and being poisoned allows {{ci|Cassiopeia}} to spam her {{ai|Twin Fang|Cassiopeia}} on you.
 
**Also, avoid being hit by other champion poisons such as {{cai|Poison Trail|Singed}}, {{cai|Deadly Venom|Twitch}} and {{cai|Toxic Shot|Teemo}}/{{ai|Noxious Trap|Teemo}}, which will also allow {{ci|Cassiopeia}} to spam her {{ai|Twin Fang|Cassiopeia}}.

As a Battlemage, Cassiopeia Cassiopeia values ability power, cooldown reduction and mana. Survivability through health, armor, magic resist and utility items are also good purchases since Cassiopeia Cassiopeia's extreme sustained damage can overpower enemies the longer she can stay alive. Thanks to Cassiopeia Cassiopeia's passive Serpentine Grace Serpentine Grace, she has no need to buy boots. In long matches this allows her to pick a sixth item as she needs, while still having equivalent movement speed to most other champions.

  • Cassiopeia Cassiopeia mostly deals magic damage; investing in magic resistance will mitigate his damage.
  • Adaptive Helm Adaptive Helm in particular is a heavy counter to Cassiopeia Cassiopeia, since it will reduce her sustained damage from repeated Twin Fang Twin Fang casts.

If they can gap close quickly and avoid Miasma Miasma entirely, their full ability combos can kill or cripple Cassiopeia Cassiopeia before she is allowed to deal with her sustained damage.
    • Zed Zed and Fizz Fizz, in particular, are the best, due to their ability to dodge Petrifying Gaze Petrifying Gaze, respectively, with Death Mark Death Mark and Playful Playful/Trickster Trickster, without being stunned or slowed at all. Kayn Kayn can also do that with his Umbral Trespass Umbral Trespass, but he needs to have damaged Cassiopeia first.
      • Be wary that none of those abilities can be used if those champions are standing upon Miasma Miasma.
  • A mage that can outrange Cassiopeia such as Vel'Koz Vel'Koz, Lux Lux, or Xerath Xerath can also deal well with her, as Cassiopeia Counters has difficulty closing the gap against them due to her lack of mobility and will mostly need to eat their harass during the laning phase.
