Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillBoth of us are weak at level 1 with one ability and no real combo, so neither side tilts the lane yet.
Level 2SylasHis Q double-detonates for poke and his W (Kingslayer) heals him on the trade, while my single mana-hungry Null Sphere can't answer — he out-trades me here.
Level 3SylasHis E grab pulls me into a point-blank Q+W combo before I have Nether Blade mana sustain to fight back.
Levels 4-5Even / skillNether Blade restores my mana off his health bar (quintupled vs champs), so I stabilize and farm under tower toward even.
Level 6Even / skillRiftwalk lets me blink out of his E grab and W dash, neutralizing his all-in and pulling us level.
First itemEven / skillCatalyst into Rod plus my Null Sphere shield and 15% Void Stone magic reduction blank his first-item AP burst — we trade evenly.
Two+ itemsEven / skillStacked Riftwalk blink burst offsets his Kingslayer sustain, but his R (Hijack) steals my ult, keeping the late AP mirror a true coin-flip.

Early game (levels 1–5)

Level 1 we are both weak, but Sylas pulls ahead at 2-3: his Q (Chain Lash) lands a delayed double-detonation for chunky poke, his W (Kingslayer) heals him on every trade, and his E grab can pull me into the combo, while my Null Sphere is a single short-range mana-sink with no Nether Blade sustain yet. Do not throw Q to poke and then sit in his range — last-hit with the Q tip and farm defensively. My Void Stone passive (15% less magic damage) softens his AP a little, but I cannot win a straight trade here, so concede the level and protect my HP.
