Read from Illaoi's seat: which stage windows this plan plays for against Sejuani.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Illaoi | Frost Armor breaks the moment a Tentacle lands, and she has no Level 1 answer to it. |
| Level 2 | Illaoi | At Level 2 her only escape, Arctic Assault, is still 18 seconds down. |
| Level 3 | Illaoi | Level 3 opens a skill window where your W-gap and E can punish her. |
| Levels 4-5 | Even / skill | Levels 4-5 are yours: her Winter's Wrath is 9s, your Harsh Lesson is 4s. |
| Level 6 | Even / skill | At 6 R Glacial Prison hard-CCs you and sets up a jungle collapse. |
| First item | Illaoi | Your first item plus a Vessel's tentacles out-damage her flat tank scaling. |
| Two+ items | Illaoi | Late she has to group, so catch her side-laning — one Vessel and the arms finish her. |
Levels 1-2 are yours: Frost Armor gives resistances and slow immunity only out of combat, so the first Tentacle that connects strips it, and Arctic Assault is 18 seconds at rank 1.
