Yuumi vs Janna

Confidence mediumUpdated Jun 9, 2026

Overview

Prioritize attaching to your ADC for sustained healing and poke support against Janna's peel.
Deny Janna's engage angles by controlling brush and maintaining safe ADC positioning.
Use your (R) to lock down targets during extended chases where Janna's peel is weaker.

Trading pattern

Stay attached to your ADC, poke with (Q), and use (E) to speed up safe disengages.
Hold (R) to root enemy follow-up or to extend fights when Janna's peel is down.
Deny brush control to limit (Q) angles and reduce enemy engage threat.

Danger windows

Respect Janna's charged (Q) knockup when she controls brush or fog for engage attempts.
Avoid detaching near (R) ultimate timing as it can reset fights and negate your all-in.
Beware of enemy ADC trades under (E) shield that amplify their damage on your ADC.

Early game

Track level 2 closely to match Janna's shield and disengage cooldowns with your attach sustain.
Keep brush warded to prevent (Q) knockup from surprising your ADC.
Coordinate wave crash timing with your ADC to create follow-up windows before Janna can reset trades.

Power spikes

Level 2: Attach sustain unlocks safer extended trades; use this to pressure Janna's shield cooldown.
Level 3: Full kit enables consistent poke and speed boosts; leverage this to force (E) shield early.
Level 6: (R) provides strong root and chase potential; use it with your ADC's follow-up for kill pressure.

Win conditions

Enable your ADC's damage by sustaining and speeding them through trades, then lock down targets with (R).
Deny enemy ADC positioning by controlling brush and vision around dragon for safer objective setups.
Roam or ward river after wave crashes to pressure mid and secure vision, returning before your ADC becomes vulnerable.
