Tank mirror — nobody dies; win the wave, the plates, and the first river fight.
Track: Ornn's Q — Volcanic Rupture (9–7s cooldown). Pillar + knockup setup — stay off walls and sidestep the line.
Read from Sejuani's seat: which stage windows this plan plays for against Ornn.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both tanks have nothing but autos and a single ability — take W, last-hit safely, and don't hand Ornn a free Bellows Breath in melee range. |
| Level 2 | Even / skill | Your Q is live but Volcanic Rupture slows you and leaves a pillar every 9 seconds — trade W poke only, and never stand with that pillar at your back. |
| Level 3 | Ornn | Full Q-W-E Frost chain is online; bait Volcanic Rupture, then Arctic Assault into the gap and Permafrost-stun him on the pillar's cooldown. |
| Levels 4-5 | Ornn | Ornn's Volcanic Rupture plus Bellows Breath plus Searing Charge burst cycle out-damages your stun trade at this tier — give the window and farm. |
| Level 6 | Ornn | His Call of the Forge God double-knockup extends his kill threat and his forge upgrades start arriving — avoid extended fights until your first item closes the stat gap. |
| First item | Even / skill | First tank item arrives and your passive Permafrost resistances absorb his poke; neither side can cleanly kill the other in a straight trade anymore. |
| Two+ items | Ornn | Two items in, your Glacial Prison range exceeds his Searing Charge, you out-CC his kit, and Ornn's immobility means he eats every stun chain you throw. |
Levels 1 and 2 are a genuine tank standoff — take W, control the wave with Winter's Wrath's slow, and Frost Armor makes you immune to Volcanic Rupture's slow until he breaks it. At Level 3 your full Q into double-W strike into Permafrost stun is live: wait for him to step up to last-hit a cannon, Arctic Assault into the creep-wave, hit both W swings to max Frost stacks, then shatter with E. Volcanic Rupture leaves a magma pillar every 9 seconds — that pillar is terrain, and Searing Charge only knocks up on a terrain collision.
