Favour timeline — the windows in Ambessa's game plan

Read from Ambessa's seat: which stage windows this plan plays for against Sion.

StageFavouredWhy
Level 1Even / skillYou have one ability and he can poke your last-hits with E armor-shred, so the opening trade is even — just farm and don't throw a Q he can step away from.
Level 2AmbessaYour Q cone plus the Sundering Slam follow-up and an empowered dash-auto out-damage his one-point Decimating Smash and cooldown-bound E.
Level 3AmbessaFull combo online: you weave Q-auto-Q faster than his cooldowns and win short trades as long as you dodge the charged knockup.
Levels 4-5Even / skillThrough 4-5 both your cooldowns are long and Soul Furnace shields then detonates after 3s, so it stays even — trade when his Q is down.
Level 6AmbessaLevel 6 is yours when his Q is down — Public Execution blinks to him, suppresses, and crashes him for a stun he cannot shield away.
First itemAmbessaEclipse plus the level 9 Q max lets Q1-auto-Q2 chunk him while you stay full, your clearest favor window before his scaling matters.
Two+ itemsSionLate is his: stacked max HP and armour blunt your physical burst, and the zombie state heals off your max health, so close before this point.

How to beat Sion as Ambessa: the early game

Level 1 is a wash: Sion shoves and chips you with Roar of the Slayer, which shreds armour and reaches 800 — and if it clips a minion the minion is knocked back through you carrying the same damage, slow and shred, so hiding behind the wave does not help. You only have one ability, so last-hit and don't throw a naked Q. The lane turns at 2 and 3: your Q cone unlocks the Sundering Slam follow-up and the passive dash weaves an empowered auto, out-trading his one-point Decimating Smash. The one thing to respect is a fully-charged Q — the knockup interrupts your dash, so bait it or sidestep.
