Farm and Scale: Early game, focus on farming and building key items like Kraken Slayer or Manamune to scale quickly. You need items to maximize your damage potential.

Stack Passive (Second Skin): Kaisa’s passive does a lot of damage when fully stacked. Auto-attack and use abilities to apply plasma stacks. When fully stacked, your next attack deals bonus magic damage, often enough to finish off a low-health enemy.

Poke with Q (Icathian Rain): Use your Q to poke enemies from range. This ability targets nearby champions and minions, dealing heavy damage when isolated on a single target. It's great for securing kills in 1v1 situations.

Use W to Snipe (Void Seeker): Kaisa’s W is a long-range skill shot that reveals and applies plasma to targets. It's perfect for sniping low-health enemies trying to escape. If evolved, landing a W lets you follow up with a quick dive thanks to the bonus range.

Ultimate to Execute (Killer Instinct): Kaisa’s ultimate lets you reposition quickly and dive into the fight, dealing bonus shielded damage. Use it to secure kills on low-health or isolated targets, but be careful not to overcommit without backup.

Evolve Abilities: Once you have enough items, evolve your abilities (Q, W, or E) for a significant power spike. Evolving Q gives more damage, W gives longer range and damage, and E boosts your mobility.

Engage Supports:

Leona: Leona's crowd control (CC) lets Kaisa follow up with her burst. Her ability to lock down enemies with stuns and roots creates perfect opportunities for Kaisa to dive in and secure kills.
Nautilus: Similar to Leona, Nautilus has great CC and can lock down enemies for Kaisa to quickly burst them down. His engage potential works well with Kaisa's aggressive playstyle.
Alistar: Alistar’s knock-ups and headbutts create a lot of opportunities for Kaisa to land her abilities and engage with her ultimate safely.
Peel and Sustain Supports:

Lulu: Lulu offers strong peel, shields, and buffs. Her ultimate can save Kaisa during all-ins, and her abilities help Kaisa stay safe while dishing out damage.
Yuumi: Yuumi's healing, shielding, and movement speed boost synergize well with Kaisa, allowing her to dive in and out of fights while being healed and buffed.
Nami: Nami’s sustain and crowd control (bubble, tidal wave) help Kaisa stay healthy during lane and offer CC to engage or disengage effectively.
Poke Supports:

Morgana: Morgana’s Black Shield (E) protects Kaisa from crowd control, while her Q (Dark Binding) sets up long-duration stuns for easy kills.
Lux: Lux’s poke and snare make it easy for Kaisa to follow up with her burst, especially with a long-range snare or ultimate combo.
