Why Akali is favored
Akali has the edge when she keeps trades short: Q and her passive punish Sylas when he approaches, while Twilight Shroud (W) can deny Kingslayer (W) and Shuriken Flip (E) can dodge his Abduct (E2). A prolonged fight can favor Sylas because he heals with W while Akali spends her limited energy, so this is a narrow +1.5pp high-elo edge rather than a hard counter.
Measured in High Elo: Akali wins 1.5pp more often than expected over 3,006 games.
How to play as Akali
Save Twilight Shroud (W) for Sylas's all-in so he cannot keep Kingslayer (W) on you; avoid taking short trades on his terms.
Akali can win short trades with Q and her passive, but her energy limits prolonged rotations; Sylas can heal through Kingslayer (W), and Sylas players say he can outlast her if a trade runs long.
Sylas Abduct (E2) can interrupt Akali E2 or R dashes, while Akali can use her own E to dodge his chain and punish its cooldown.
How to play as Sylas
Avoid short trades in the first few levels; wait for Akali to spend or miss Shuriken Flip (E) before committing, since landing it sets up her burst.
When Akali opens with Perfect Execution (R), use Abscond (E1) or Flash immediately if needed to dodge the follow-up Shuriken Flip (E).
