Cassiopeia is a champion in League of Legends.[1]

Abilities

Edit

Serpentine Grace

Serpentine Grace

Innate: Cassiopeia gains 4 − 72 (based on level) Movement speed icon bonus movement speed, but she cannot purchase Boots.

Info
  • The movement speed from Serpentine Grace is worth 48 Gold 48 per level, up to a maximum of 864 Gold 864 at level 18.
  • Without other movement speed modifiers taken into account, Serpentine Grace grants Cassiopeia a total of 332 − 400 (based on level) Movement speed icon movement speed.
  • As Magical Footwear Magical Footwear requires boots, the rune will be replaced with Triple Tonic Triple Tonic.

Map-Specific Differences
Arena icon Arena differences edit
  • New Effect: Increases the Guardian item limit to 2.
  • Bonus movement speed changed to 2.8 − 50.4 (based on level).

Edit

Noxious Blast

Noxious Blast

Active: Cassiopeia creates a blast at the target location that explodes after a 0.4-second delay. Enemies within the blast are Poison icon poisoned for 3 seconds, taking magic damage every 0.429 seconds over the duration.

Total Magic Damage:
75 / 110 / 145 / 180 / 215 (+ 90% AP)
Magic Damage Per Tick:
10.71 / 15.71 / 20.71 / 25.71 / 30.71 (+ 12.86% AP)

If Noxious Blast hits an enemy Champion icon champion, Cassiopeia gains Movement speed icon bonus movement speed that decays over 3 seconds.

Bonus Movement Speed:
30 / 35 / 40 / 45 / 50%

Info
  • Noxious Blast always uses quick cast, regardless of player settings.
  • The damage inflicted by Noxious Blast is calculated as follows: damage / 7 ticks rounded down to the nearest integer.
    • For example: with 0 bonus AP Noxious Blast inflicts 75 damages over 7 ticks of damage, so 75/7 (≈10.71) deals first of all 10 damage, then (2 × 75/7)  −  10 (≈11.43) deals in a second time 11 damages, then (3 × 75/7)  −  10  −  11 (≈11.14) deals in a third time 11 damages, and so on.
  • The damage displayed for Noxious Blast DOT (Damage_over_time) always remains constant and corresponds to the previously mentioned formula: damage / 7 ticks rounded down to the nearest integer. It's important not to confuse the consistent displayed damage with the actual damage, which is updated with each tick, see tick and updates.
    • With the same example as above, the damage displayed is always 10.
  • Occasionally, Noxious Blast may not deal the displayed damage. This discrepancy occurs when the calculated damage falls between 0.5 and 1. In such cases, rounding to the nearest integer, specifically rounding up, creates a 1-point difference. It's important to note that the damage is rounded down to the nearest integer.
    • For example: with a Blasting Wand's Blasting Wand's, Noxious Blast shows so rounded to the nearest integer 116 magic damage, but really deals using the formula above 115 magic damage.
  • (bug) When Cassiopeia has precisely 20 bonus AP or 40 bonus AP. In this scenario, Noxious Blast may inflict 1 less damage than intended. Importantly, this bug occurs independently of rounding considerations.
  • PENDING FOR TEST: Enemies within the blast of Noxious Blast are Poison icon poisoned for something between 3.2 and 3.3 seconds.

Edit

Miasma

Miasma

Active: Cassiopeia spews forth 8 bolts of venom in an arc at the target location, creating toxic clouds at the area for 5 seconds.

Enemies within the clouds are Poison icon poisoned to take magic damage every 0.263 seconds and become Grounded icon grounded and Slow icon slowed by an amount that decays over the area's duration.

Magic Damage Per Second:
20 / 25 / 30 / 35 / 40 (+ 15% AP)
Total Magic Damage:
100 / 125 / 150 / 175 / 200 (+ 75% AP)
Slow:
40 / 50 / 60 / 70 / 80%

Miasma will cast at max range if cast beyond that.

Info
  • Miasma's Slow icon slow and Grounded icon ground debuffs are each marked as non-dispellable, so they are not removed by most Remove Scurvy cleanses. Each is however allowed to be removed by cleanses that also grant immunity to the debuff type, such as Olaf's Olaf's Ragnarok Ragnarok.
  • If a target becomes Untargetable icon untargetable while affected by the Grounded icon ground, the debuff will refresh to 0.25 seconds.
  • Wind Wall Wind Wall will block the portion of Miasma it destroys.
  • Miasma inflicts 5 / 6.25 / 7.5 / 8.75 / 10 (+ 3.75% AP) magic damage per tick, and in fact because there is 19 ticks and not 20 ticks, the total magic damage is currently not 100 / 125 / 150 / 175 / 200 (+ 75% AP) but 95 / 118.75 / 142.5 / 166.25 / 190 (+ 71.25% AP).
    • (bug) Sometimes Miasma randomly inflicts only 18 ticks of damage.

Map-Specific Differences
Arena icon Arena differences edit
  • Cooldown changed to 28 / 26 / 24 / 22 / 20 seconds.

Edit

Twin Fang

Twin Fang

Active: Cassiopeia launches her fangs at the target enemy that deal 52 − 120 (based on level) (+ 10% AP) magic damage. If this kills the target, Twin Fang's Mana icon mana cost is refunded.

Against a Poison icon poisoned target, Twin Fang deals bonus magic damage and Heal power icon heals Cassiopeia. The heal is reduced by 75% against Minion icon minions and small and medium Monster icon monsters.

Bonus Magic Damage:
20 / 40 / 60 / 80 / 100 (+ 60% AP)
Total Enhanced Damage:
52 − 120 (based on level) (+ 20 / 40 / 60 / 80 / 100) (+ 70% AP)
Heal:
10 / 11.5 / 13 / 14.5 / 16% AP
Reduced Heal:
2.5 / 2.875 / 3.25 / 3.625 / 4% AP

Info
  • Upon reaching the target, Twin Fang will wait for an ongoing Noxious Blast Noxious Blast to explode before dealing its damage.
  • Twin Fang's damage against poisoned targets:
    • When maxed first: 72 − 220 (based on level) (+ 70% AP).
    • When maxed second: 72 − 220 (based on level) (+ 70% AP).
    • When maxed last: 72 − 220 (based on level) (+ 70% AP).
  • Twin Fang's cast indicator is incorrectly adding her own radius to the range like an Range model edge range ability, and therefore slightly larger than the actual cast range Twin Fang can cast at.
  • If the target becomes Untargetable icon untargetable, Death dies, or is too far away or no longer in Sight icon sight during the cast time, this ability will cancel but does not go on Cooldown icon cooldown nor pay its cost (if applicable).

Map-Specific Differences
Arena icon Arena differences edit
  • Poisoned AP ratio changed to 45% AP.

Edit

Petrifying Gaze

Petrifying Gaze

Active: Cassiopeia blasts enemies in a cone in the target direction, dealing magic damage to enemies struck within and Slow icon slowing them by 40% for 2 seconds. Enemies with their facing direction towards her are instead Stun icon stunned for the same duration.

Magic Damage:
150 / 250 / 350 (+ 50% AP)

Info
  • Cassiopeia will turn to face the target direction over the cast time.
  • This ability will cast from wherever the caster is at the end of the cast time.
    • Petrifying Gaze's target direction will change if Cassiopeia's facing direction changes during the cast time (i.e. through Airborne icon knockbacks).
  • The facing direction of champions whose abilities/animations cause them to lock their facing or spin is always the direction they are moving in. For abilities that cause the champion to spin in place (e.g. Death Lotus Death Lotus, Judgment Judgment) it will factor the direction they were facing on cast.
    • Lucian's Lucian's The Culling The Culling is an exception and his facing direction is actually considered to be the direction he is facing.

Map-Specific Differences
Arena icon Arena differences edit
  • Base damage changed to 100 / 175 / 250.
  • AP ratio changed to 40% AP.

Cassiopeia OriginalSkin
Original
RP 880
14.12.2010
Cassiopeia is a deadly creature bent on manipulating others to her sinister will. Youngest and most beautiful daughter of the noble Du Couteau family of Noxus, she ventured deep into the crypts beneath Shurima in search of ancient power. There, she was bitten by a gruesome tomb guardian, whose venom transformed her into a viper-like predator. Cunning and agile, Cassiopeia now slithers under the veil of night, petrifying her enemies with her baleful gaze.
