Builds by level

Every combination of Cassiopeia's own traits that a comp of the chosen level can reach, ranked by the DPS of its best 3-item build against three dummies with the team's shred, sunder and burn already on them. Numbers open the DPS Calculator with the same inputs. Levels 4 to 7 only use champions you can find at that level: up to 2-costs at level 4, 3-costs at levels 5 and 6, 4-costs at level 7.

  • attack animation

  • cast window (mana locked)
  • effect

First cast at 4.53 s with 0.75 attacks per second. Items, traits and damage taken change the mana pace; the cast, effect and channel windows do not.

Step by step, in words
  1. Mana reaches 30/30: the cast starts and the mana lock goes on (no mana from attacks, ticks or damage taken).
  2. 0.00 to 1.01 s: cast window. The unit plays its cast animation and its return to idle; it cannot auto attack.
  3. 0.25 s: the ability's effect fires (projectile launch, damage, shield...).
  4. 1.01 s: unlock. Mana starts again (overflow kept) and a fresh attack starts from zero; it lands at 1.46 s at base attack speed (the attack delay is 34% of the attack animation).
  5. Attack loop: the attack lands at 34% of the attack animation (mana granted) and unlocks at 40%; a cast that becomes possible at the landing starts at that unlock point, cutting the rest of the attack.
  6. Mana gain: 7 per attack and 2 per second; combat starts at 0/30.
  7. Overflow is banked: mana past 30 from attacks or regen is kept through the cast (28/30 plus 7 casts and comes back with 5). Same rule for every champion; only the amounts differ by role.

// Itemized Roles

Ranged AP CarrySolidBlue BuffJeweled GauntletGiant Slayer

3-cost ranged AP Caster (game role tag, range 4). As the comp's damage dealer it takes the best calculated damage items. Mana lock 1.01 s per cast against a 4.5 s fill (18% locked). Casts per minute at base speed 11; with Spear of Shojin 15.6, Blue Buff 16.4, a +45% attack speed item 13.7. Blue Buff and Spear of Shojin are within 5% of each other, so either keeps the loop rolling; the default mana-per-attack set stays.

Ranged AD SupportSituationalLast WhisperMorellonomiconSpear of Shojin

3-cost ranged AP Caster (game role tag, range 4). It can hold the team Sunder and Burn items for an AD comp; its own AP damage does not profit from the debuff. Mana lock 1.01 s per cast against a 4.5 s fill (18% locked). Casts per minute at base speed 11; with Spear of Shojin 15.6, Blue Buff 16.4, a +45% attack speed item 13.7. Blue Buff and Spear of Shojin are within 5% of each other, so either keeps the loop rolling; the default mana-per-attack set stays. One Sunder item and one Burn item for the team, plus the third item that adds the most calculated damage for Cassiopeia (523 DPS at 2 stars against three 2-star tanks). Ionic Spark, Evenshroud and Sunfire Cape are left out: at range 4 their aura would not reach the enemies.

Ranged AP SupportSituationalVoid StaffRed BuffBlue Buff

3-cost ranged AP Caster (game role tag, range 4). When another champion carries, it holds the team Shred/Sunder and Burn items. Mana lock 1.01 s per cast against a 4.5 s fill (18% locked). Casts per minute at base speed 11; with Spear of Shojin 15.6, Blue Buff 16.4, a +45% attack speed item 13.7. Blue Buff and Spear of Shojin are within 5% of each other, so either keeps the loop rolling; the default mana-per-attack set stays. One Shred item and one Burn item for the team, plus the third item that adds the most calculated damage for Cassiopeia (648 DPS at 2 stars against three 2-star tanks). Ionic Spark, Evenshroud and Sunfire Cape are left out: at range 4 their aura would not reach the enemies.
