Cassiopeia is a powerful control mage who excels at dealing consistent damage through poison and petrification abilities. Unable to purchase boots due to her passive, she gains movement speed per level and can utilize an extra item slot for increased late-game scaling.

Core Abilities:

  • Passive (Snake Grace): Gains movement speed per level, cannot buy boots
  • Q (Poison Explosion): Area poison damage, grants movement speed
  • W (Miasma): Creates poison clouds that ground and slow enemies
  • E (Twin Fang): Single-target spell with low cooldown, enhanced against poisoned targets
  • R (Petrifying Gaze): Stuns enemies facing Cassiopeia, slows others

Strengths:

  • Exceptional sustained damage output
  • Strong self-peel abilities
  • Excellent late-game scaling
  • Powerful kiting potential

Weaknesses:

  • Mana-intensive early game
  • Shorter range than typical mages
  • High skill ceiling
  • Position-dependent

Optimal Skill Order:

  1. E (Twin Fang)
  2. Q (Poison Explosion)
  3. W (Miasma) Max Order: R > E > Q > W

Core Combo: Q -> AA -> E -> E -> AA -> E

Strong Against:

  • Linear-engaging assassins (LeBlanc)
  • Short-range mages (Sylas, Ahri)

Weak Against:

  • Mobile assassins (Zed)
  • Long-range mages (Viktor, Syndra)

Early Game Tips:

  • Use E to last hit minions (mana refund on kills)
  • Conserve mana for important trades
  • Focus on farming and scaling
  • Position carefully due to limited range

Effective Laning:

  • Look for Q > E combos when enemies step forward
  • Use W to zone enemies from important areas
  • Save ulti for self-peel or jungle ganks
  • Maintain safe distance while farming

Late Game:

  • Focus on positioning in teamfights
  • Use ultimate to counter enemy engages
  • Layer CC with teammates
  • Maximize DPS on poisoned targets

Positioning is crucial for success with Cassiopeia. Stay behind frontline teammates, use terrain to your advantage, and always be ready to counter-engage with your ultimate.
