Daughter of the Void
Kai’Sa is a hard-to-classify marksman. She usually plays bot lane and sometimes shows up mid, and her build path changes what her abilities actually do. Her passive, Second Skin, builds Plasma on targets through basic attacks. At full stacks, the Plasma detonates for significant bonus magic damage. Allied immobilizing effects also add stacks, so crowd-control supports pair especially well with her. Once her item stats reach the required thresholds, the same passive turns her Q, W and E into evolved Living Weapon versions.
Icathian Rain launches a volley of homing missiles that can strip down isolated targets, and its evolution fires even more of them. Void Seeker is a long-range skillshot that places Plasma stacks from a distance. After evolving, it applies more marks and returns cooldown when it hits champions. Supercharge turns movement speed into a short burst of attack speed. Once evolved, it also grants brief invisibility, giving her a repositioning option most marksmen lack.
Killer Instinct brings the kit together. It is a long dash toward a marked enemy champion, letting Kai’Sa chase, slip past key spells, or dive into the backline. This makes her a marksman who can scale like a traditional ADC in teamfights and also flank like an assassin once her evolutions are online. Her 525 attack range is fairly short, though, so she has to manage her positioning carefully.
Kai’Sa is a good fit for players who enjoy flexible builds and who like to earn their aggression through item breakpoints. She offers steady mixed damage and the uncommon ability to dive onto targets herself.
