Read from Sion's seat: which stage windows this plan plays for against Tryndamere.
This is Sion's own plan; across 1,766 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Tryndamere | Tryndamere free-autos to max fury at level 1 with no ability cost and your W is not yet available — farming with Q tip range avoids giving him a free crit burst. |
| Level 2 | Even / skill | W-shield comes online and absorbs his crit autos; small trades now cost him more fury than they gain him, evening the field. |
| Level 3 | Sion | E-shred into a full-charge Q knockup is live — he has no dash or dodge to avoid the stun if you commit from your side of the wave. |
| Levels 4-5 | Even / skill | His E is the trade-breaker: he spins through your charge telegraph to dodge the Q or escape after a bad trade. Only charge Q when his E is visibly on cooldown. |
| Level 6 | Even / skill | Both ultimates create all-in uncertainty — your R is a chase and engage tool but his R keeps him alive through your follow-ups. Track the 110-second R cooldown before every commit. |
| First item | Sion | Heartsteel HP and a large W-shield let you absorb a full crit burst and brawl back — buy anti-heal first to gut his fury passive regeneration during trades. |
| Two+ items | Even / skill | His crit DPS still kills you if you fight W-down; stay even by respecting his E gap-close and never all-in while Undying Rage is available. |
Level 1 is his best window — Tryndamere auto-attacks freely to stack fury before your W is even a button, and his crits hit hardest on a low-HP pool. Stay back, last-hit with the tip of your Q, and do not let him auto you three times into a confident all-in. At level 2 your W-shield comes online and the dynamic shifts immediately: pop W before he spins in and his crit burst hits the shield instead of your HP bar. By level 3 you have E to shred his armor — bait him onto your side of the wave, E-shred, then begin a charged Q. He has no hard dodge on your stun, so a clean full-charge lands for massive damage and sets the tempo.
