Favour timeline — who owns each window

StageFavouredWhy
Level 1TrundleQ Chomp bites her AD before she has frost stacks loaded, and the flat damage plus AS slow wins the very first auto-trade pattern at level 1.
Level 2TrundleW Frozen Domain gives you move speed and healing from passive kills before Sejuani has reliable frost stacking or her E cooldown short enough to punish your zone fighting.
Level 3Even / skillWith Q+W+E all online the trade is genuinely contested: you control ground with W and cut escape with Pillar, but her frost stacks accumulate through any ability contact and she can chain into E stun to break your domain — neither side has a clean win.
Levels 4-5Even / skillSejuani's frost application becomes more consistent at higher levels and Permafrost's stun cooldown shortens with ranks — she can now reliably interrupt your Frozen Domain window mid-trade, erasing your duel advantage.
Level 6SejuaniGlacial Prison online changes the fight geometry entirely: she fires R, you are stunned out of Frozen Domain, she W's twice for percent-HP damage, and E finishes the CC chain — your Subjugate resist-drain cannot outpace that pattern.
First itemSejuaniHer first item (Heartsteel or Sunfire) amplifies her percent-HP damage with bonus max-HP stacking and Immolate chip — she wins extended trades by volume of unavoidable percent-HP hits, and the armor you drain from R does not reduce that damage type.
Two+ itemsSejuaniTwo items deep, Sejuani's Winter's Wrath burst per full combo exceeds what Subjugate's resist-drain and your passive healing can recover, and her R stun shuts down any split-push or side-lane all-in you attempt without jungle backup.

Early game (levels 1–5)

You win the very early levels on raw kit pressure alone: Chomp bites AD off Sejuani's auto attempts and the AS slow stops her from quickly stacking Permafrost with consecutive autos. Drop W at your feet and keep trades short — bite once, weave an auto inside the zone, then back off before she reaches three frost stacks and fires E. She has no gap-close, so you set the engagement distance. Respect the E stun range and never stand directly on top of her when a frost stack is already showing on your health bar.
