Ivern vs Lillia

Place your groves, then go gank while they grow: Friend of the Forest (passive) lets you free the camp without fighting it once the grove is fully grown.

After landing Rootcaller (Q), ping your team: allies who attack the rooted target dash into attack range, and you can dash to the target by recasting.

Cast Triggerseed (E) on the ally who engages: the shield explodes after a moment and slows enemies around them.

Recast Daisy! (R) to give her a target: her 3rd consecutive auto on the same champion knocks every enemy hit into the air.

Against Blooming Blows (Q), stick to her or back out of range: only the outer edge of the zone adds true damage.

Get out of the center of Watch Out! Eep! (W): the zone deals much more damage there than at the edge.

Dodge her spells, even Swirlseed (E), which rolls to the first enemy: each one marks you for Lilting Lullaby (R), which puts every marked enemy to sleep.

If you have CC, use it on her: with no dash, she relies on the move speed Blooming Blows (Q) gives her for each spell that hits.
