Learn how to play with Cassiopeia with these essential tips.
Tags:
All
Follow up when Cassiopeia casts her W (Miasma) on enemies. This ability not only poisons but also grounds enemies, preventing them from using dash or blink abilities. Use this opportunity to land your skillshots, as enemies can't use mobility to dodge.
Team Fight Skirmish
Position on the opposite side of enemies when Cassiopeia uses her R (Petrifying Gaze). This forces enemies to either face her and get stunned or face you and only receive a slow, maximizing the effectiveness of her ultimate.
Team Fight
Cassiopeia's damage comes from applying poison with Q or W, then spamming E. When she lands poison on an enemy, she can deal rapid damage with E, which also heals her. Engage when you see enemies poisoned as this is her peak damage window.
Basic Skirmish Team Fight
Cassiopeia is one of the strongest late-game champions. Even if she falls behind early, protect her and help her farm safely. Her damage output becomes tremendous past 25 minutes when she has multiple items.
Basic Late Game
When Cassiopeia lands her Q on an enemy champion, she gains 30-50% movement speed for 3 seconds. Use this window to engage or follow up with her, as she can reposition more quickly during this time.
Skirmish Team Fight
Prioritize ganking for Cassiopeia, as she has no mobility spells to escape. Her only self-peel is her R stun and W slow, which have long cooldowns. Ward for her and provide protection, especially in the early game.
Lane Phase
Fight alongside Cassiopeia in jungle corridors and tight spaces. Her W covers a greater percentage of the walkable area, and her R can more easily stun multiple enemies when they have limited movement options.
Advanced Skirmish Team Fight
Watch Cassiopeia's mana bar during fights. She runs out of mana quickly in the early game, which severely limits her damage. If her mana is below 25%, avoid engaging unless you're confident you can win without her sustained damage.
