Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillTrundle's Q bite deals max-HP damage even at Level 1 and your W-shield is not yet up — charge in fog and do not auto-trade freely.
Level 2Even / skillW-shield now absorbs his Q bite chunk; short trades start to favor you if you pop the shield on his first auto and detonate in return.
Level 3SionFull kit — charged Q knockup into E armor-shred deletes his resistances before his Q bites can compound; this is your first clean window.
Levels 4-5Even / skillTrade around Subjugate's cooldown: when it is down push the pattern hard, when it is up give nothing and let the wave reset.
Level 6Even / skillSubjugate is live at 6 and steals a percent of your armor and MR — never all-in while it is available; wait for the cooldown window.
First itemSionHeartsteel compounding HP makes each W-shield value larger and your zombie passive harder to ignore — force fights strictly on Subjugate's cooldown.
Two+ itemsEven / skillHis Q bite scales with your raw HP total late, so anti-heal (Thornmail) is mandatory to keep the drain manageable; close through objectives rather than raw 1v1 brawls.

Early game (levels 1–5)

At Level 1 Trundle has the cleaner opener — his Q bite deals max-HP damage on a short cooldown while your W-shield has not yet come online to absorb it. Stay at the tip of your Q range and charge in brush so he cannot see the wind-up; do not walk into his auto range to trade freely. At Level 2 your W-shield changes the math significantly: pop it right before his Q bite lands and the shield eats the max-HP chunk while your detonation ticks him back. Level 3 is your first real opportunity — get all three abilities and look for a charged Q knockup into immediate E armor-shred; if it lands he is at a heavy HP deficit before his Q bite can recover the difference.
