Favour timeline — the windows in Sylas's game plan

Read from Sylas's seat: which stage windows this plan plays for against Irelia.

StageFavouredWhy
Level 1Even / skillHer Bladesurge pokes and heals off the wave and you have no second ability to answer with — farm at Q tip and bank both E charges for the level 2 window.
Level 2SylasE2 hooks her mid-Q-dash: you stun her before the fifth stack triggers, W burst-heals through her shred, and she loses the trade she came to win.
Level 3IreliaFull attack-speed stacks plus Bladesurge resets give her the damage to chunk you in short exchanges — use E1 on every engage and never extend the fight.
Levels 4-5IreliaIrelia at full Ionian Fervor with Bladesurge resets live is the most dangerous she gets — stay back, let the stacks decay off minions, and trade only when Flawless Duet is visibly down.
Level 6Even / skillHijack copies Vanguard's Edge: the blade-wall root disrupts her dash pattern and you can all-in with her own ultimate while hers sits on cooldown.
First itemIreliaHer first-item Trinity Force or Blade of the Ruined King burst outpaces Riftmaker in the short trades she prefers — look to roam rather than keep grinding the 1v1.
Two+ itemsSylasAt two-plus items you outscale her in teamfights by stealing her R off cooldown and using it into grouped enemies — she cannot replicate that swing with your kit.

How to beat Irelia as Sylas: the early game

Level 1 is a wash — her Bladesurge pokes and heals off the wave and you cannot punish it yet, so last-hit at Q range and keep your E charges full. The moment you hit level 2, E is your whole gameplan: she will Bladesurge in to build Ionian Fervor, so pre-aim the E2 chain to catch her mid-dash, land on her, and immediately W for the burst-heal. That sequence ends the trade before her attack speed compounds. Never use E1 offensively without E2 ready — an E-less Sylas against Irelia at level 2 is just a melee mage with no escape.
