When facing Cassiopeia's top counters like Syndra, Veigar, Ekko, consider adjusting your situational items to increase survivability and match their damage output. If counter champions are building high damage, prioritize magic resistance items against AP threats in your situational item slots to reduce burst damage and improve trading potential. Your core build provides strong damage output. Against tanky counter picks, consider penetration items or percentage-based damage from your situational options to maintain kill pressure. Adapt your final build slots with items like Rabadon's Deathcap or Rod of Ages based on which counter champions you're facing and their itemization patterns. Monitor enemy builds and adjust accordingly for optimal Cassiopeia performance.
