Kai'Sa Item Build
Kai'Sa's item purchases literally rewrite her spells, and where the Rift lets her tune that evolution to a specific matchup, the Abyss simply wants the damage and attack speed that upgrade Icathian Rain into a clump-shredder. Second Skin stacks Plasma faster the more she attacks, so every point of offense loops back into her passive burst. She skips the perfect counter-item for the stats that upgrade her missiles fastest and lets a fight that never resets do the rest.
Best Kai'Sa Runes
Lethal Tempo favors a marksman who wants to keep firing into the Abyss clump, where Kai'Sa stacks plasma across a grouped team before diving the weakest link. Her kit thrives on staying alive to reach her evolves, so the page supports the uptime and safety that let her fire and reposition around the endless fight.

Kai'Sa Skill Order
Supercharge takes over from 8 onward and keeps taking points through 15, the reverse of Rift practice where Void Seeker is the second ability finished. The Abyss rewards attack speed and the sustained fire it feeds, so Void Seeker sits on its opening rank until 16.
Kai'Sa ARAM Abilities
Worth knowing on Second Skin: allied crowd control also stacks her plasma, so a good engage support speeds up every detonation without her lifting a finger. Void Seeker is the long range setup, a missile that tags targets with those same marks from a screen away.
