Olaf should pressure Illaoi early to deny her calm scaling and force extended fights where he excels.
Use Olaf's high early agency and lane pressure to prevent Illaoi from establishing tentacle zones and spirit pull angles.
This is a snowball matchup where Olaf aims to dominate early and leverage his anti-CC all-ins to punish Illaoi's low mobility.
Trading pattern
Initiate trades by landing (Q) and picking it up repeatedly to maintain chase and pressure Illaoi.
Use (R) to ignore Illaoi's limited crowd control and commit to all-ins only when she cannot disengage effectively.
Punish Illaoi heavily after she misses (E) or when tentacles are cleared, as her threat drops sharply then.
Danger windows
Be cautious when Illaoi lands (E) spirit pull near tentacles, as this sets up her strongest trades.
Olaf is vulnerable after (R) ends since he can be kited and loses his crowd control immunity.
Avoid fighting Illaoi inside her fully established tentacle zones where she can maximize damage and healing.
Early game
Start by landing (Q) axes to slow Illaoi and force her into unfavorable trades before she sets up tentacles.
Use (W) shield and lifesteal to sustain through Illaoi's poke and stay healthy for extended trades.
Avoid chasing Illaoi into her tentacle zones early; instead, control space to limit her (E) angles and punish missed spirit pulls.
Power spikes
At level 6, use (R) to gain crowd control immunity and force straight-line fights where Illaoi struggles to kite.
After completing the first fighter item, pressure the side lane aggressively to extend fights and punish Illaoi's missed disengages.
Respect Illaoi's level 6 (R) which can turn fights if she has multiple tentacles and enemies commit into her zone; avoid clustering near her tentacles.
Win conditions
Win by landing repeated (Q) axes and forcing extended melee fights where (R) negates Illaoi's limited peel.
Deny Illaoi the chance to set up tentacle zones and spirit pulls by pressuring early and clearing tentacles.
Use side-lane pressure and all-in potential post-level 6 and first item to snowball and prevent Illaoi from scaling effectively.
