Patch History

v6.10

Q and W ranges up. W cooldown decreased.

One of the larger Midseason mage updates, Cassiopeia’s strengths as an immobilizing controller have been muted by a rather weak release state. Low ranges across her poisons appear to be the culprit, as Cassi quite literally lives or dies on her ability to access Noxious Blast’s burst of speed (or Miasma’s grounding). Add in some bonus usability to her poisons and Cassiopeia will see herself actually able to play her keep-away kite game without being overrun.

Noxious Blast.png Q - Noxious Blast

RANGE : 750 850
SAVOR THE MOMENT : Noxious Blast’s movement speed bonus takes longer to decay

BRINGING IT BACK : No longer stops upon hitting terrain


5/9/2016 Balance Update

Cassiopeia's update shaved a little too much power off of Twin Fang. Rather than raw damage buffs, we're giving back a bit of its uptime.

Twin Fang.png E - Twin Fang

Cooldown : 0.9 seconds 0.75 seconds
COST : 60/65/70/75/80 mana 40/45/50/55/60 mana
RANGE : 550 (from Cassiopeia's hitbox edge to her opponent's) 700 (from Cassiopeia's hitbox center to her opponent's.) Overall, slight increase against small targets and slight decrease against large targets.


v6.9

True to her half-snake nature, Cassiopeia bears twin identities of “poison mage” and “lightning-fast viper strikes.” However, the high-input gameplay of Twin Fang has left Cassiopeia wanting for greater impact in her poisons, instead viewing them as a gating condition for her combo damage.

Rather than giving her more damaging poisons (Singed has that market cornered), we’ve sharpened Cassiopeia’s poison fantasy by linking Miasma to another snake fantasy: immobilization. The new Miasma lets Cassiopeia weaponize her own immobility by bringing opponents to her level. By limiting the ability power of champions to leave her kill zone, Cassiopeia dictates the ranges of an engagement, keeping foes at a distance where she can wail on them safely. Should her opponents play around Miasma, however, Cassiopeia loses that control and faces swift punishment from the champions she sought to keep at bay.

v5.10

"These are two changes aimed at two different things, so we'll explain. First, while we did intend for late-game Cass to be an unstoppable force of a half-snake, the scaling heal on Twin Fang makes her borderline unkillable for some team compositions (particularly given her zone control). Second, when we were looking for ways to trim power on Cass, we saw that her champion update came right before our big refactor of the mana regeneration stat of the 2015 season (with most champions ending up with less mana regen in general). Given that these original numbers were tuned around competing mid-laners of the time (and higher baseline mana regeneration expectations like Athene's Unholy Grail), we decided to modernize accordingly. Cassi's still going to hit like a truck in the lategame - we just wanted to give more windows of opportunity for opponents to take advantage."

  • Twin Fang.png E - Twin Fang
    • MANA REFUND : If Twin Fang kills the target, it refunds its mana cost plus 3% of Cassiopeia's maximum mana 1.5% of Cassiopeia's maximum mana

v5.6
Cassiopeia gets less AP when combined with %AP amplifying effects

"Last patch we modified how the first Dragon buff interacts with Rabadon's Deathcap (from multiplicative to additive, with an expected ~1-2% ability power change), but failed to document the larger hit to Cassiopeia, who was tripling (quadrupling?) down on it with her passive, Dragon buff, masteries, and Rabadon's Deathcap. We're documenting it now and realize this is late game Cassi nerf, but we're watching how this shakes out first. "
  • LATE GAME CASSI NERF : Dragon buff and Rabadon's Deathcap now interact additively rather than multiplicatively. When these two ability power % modifications (and masteries) interact with Cassiopeia passive, they now give roughly ~12% less bonus ability power at late, late game.

v5.2
Q and E have higher mana costs.

"As a lane bully, one wrong move against Cassiopeia can lose you a ton of HP and send you ducking for cover beneath your tower (or just packing your bags and going home). While it's not impossible to fight back, Aspect of the Serpent's healing just reinforces this non-stop lane bully tactic without much in terms of tradeoffs (thanks to Twin Fang's mana recovery). Increasing Cass's mana costs on Q and E should make it more of a calculated decision to harass or sustain, giving savvy opponents more time to formulate a counter-attack (or at least walk back to lane)."

    • CLARITY! : Twin Fang's tooltip now always displays the amount of mana it will restore

v4.21
Aspect of the Serpent now gains stacks over time and every second an enemy champion is poisoned (rather than on poisoned unit kill or when using Twin Fangs on an enemy champ). Twin Fang now adds a debuff that amplifies poison damage on the target.

"Cassi's recent update definitely gave her the late-game we intended, but at two great costs: her early-game strength, and her identity as a 'Poison Mage.' We're trying to smooth out a bit of Cassiopeia's power here with some early buffs alongside some guaranteed scaling on her passive so that she can hit her early-mid-lategame fantasy (that is now a word) at the appropriate times. In short, we're looking to reach a middle ground between the update and her original feel of killing you slowly with venoms. Just quicker. (And with more venoms)."
  • Aspect of the Serpent.png Passive - Aspect of the Serpent
    • STACK CITY : Cassiopeia builds a stack of Aspect of the Serpent on every poisoned unit kill or on Twin Fang cast on enemy champion once every 6 seconds (10 times per minute) and for every second that an enemy champion is poisoned.
    • IT'S A BUFF WE PROMISE : Cassiopeia gains special bonuses at 75/200/400 stacks 100/250/500 stacks. The new breakpoints will be hit sooner than the old ones based on the new stacking mechanics (above).
  • Noxious Blast.png Q - Noxious Blast

v4.17
Some small buffs to Cass's mana, Q's damage scales better with AP, and E's resetting its cooldowns correctly.

"We know Cass isn't doing great on the live environment, but we also want to make sure we don't react too quickly as players are learning a champion and then that champion goes on to demolish everyone (*cough* Kassadin *cough*). Still, we can give Cass a little bump as we watch her being picked up. This might be a conversation we'll revisit next patch! "

v4.16
Cassi's received a gameplay update! Focusing on her new passive Aspect of the Serpent, she's now more about stacking up poisons for massive end-game scaling than being a dominant laning force. Mana costs, cooldowns, base damage and ratios have all been mixed up to compensate - read below for the numbers!

"Cassiopeia's high DPS has always sat alongside her poison as defining characteristics of the serpent lady. Historically however, these traits have led to oppressive gameplay that's as challenging for the opponent to deal with as it is to understand (THANKS DAMAGE OVER TIME). To preserve both sides of what makes Cassi unique, we realized we had to modify the relationship between the two.
In this update, the key to Cassiopeia's heavy-hitting damage potential lies within her new passive, Aspect of the Serpent. Cassi builds power throughout the game as she poisons enemy champions, unlocking stat bonuses to fuel her (now more powerful) Twin Fang. This new aspect (heh) of growing her end-game scaling allows us to solidly push her into the 'completely-absurd-damage-potential' space she's currently hanging around. This comes at the cost of some early game power, but make no mistake - you can expect to see a late-game Cassiopeia as one of the most potent damage threats in the League."
