Aphelios vs Kai'Sa

Confidence highUpdated Jun 7, 2026

Overview

This lane turns on managing Aphelios's weapon pairs to punish Kai'Sa's short-range all-ins.
Aphelios wins extended trades and wave control with Calibrum and Infernum, while Kai'Sa needs isolated targets to commit.
Hold wave near your side to force Kai'Sa into risky dashes for CS or all-ins without support setup.

Trading pattern

Step forward to auto Kai'Sa during last-hit animations only if her support can't immediately punish.
Use Calibrum poke when Kai'Sa moves up for CS, especially when her (E) dash is on cooldown.
Avoid trades when your Gravitum root is spent or your support isn't ready to follow up on your weapon state.

Danger windows

Respect (R) reposition after plasma stacks; avoid isolated positioning that enables her all-in.
Beware when enemy support controls brush or river, as Kai'Sa can follow up your step forward with (R) and support CC.
Avoid extended trades when (E) dash is available, as she can reposition or disengage safely.

Early game

Use the first three waves to track (E) usage and avoid stepping up when it's active for her dash safety.
Punish Kai'Sa's last hits on low-health caster minions with Calibrum poke if enemy support cannot zone.
Keep wave thinned to reduce (Q) isolated damage and limit her all-in windows after level 2.

Power spikes

Strong weapon pairs create temporary spikes; trade only when Calibrum or Infernum is active to maximize poke and wave punish.
Level 6 (R) with the right weapon amplifies burst or poke; use it to start trades when Kai'Sa lacks (R) follow-up.
First completed marksman item increases safe poke and wave control, pressuring Kai'Sa before she hits item thresholds.

Win conditions

Convert Calibrum and Infernum poke into CS leads by forcing Kai'Sa off the wave during last hits.
Use wave crashes timed with strong weapon pairs to secure turret plates and dragon vision control.
Scale into teamfights with Crescendum DPS windows, relying on support peel to safely output damage against Kai'Sa's dive threat.
