Passive — never cast
Howling Gale
By creating a localized change in pressure and temperature, Janna is able to create a small storm that grows in size with time. She can activate the spell again to release the storm. On release this storm will fly towards the direction it was cast in, dealing damage and knocking away any enemies in its path.

Zephyr
Janna summons an air elemental that passively increases her Move Speed and enables her to pass through units. She may also activate this ability to deal damage and slow an enemy's Move Speed.

Counter plan — how to beat Janna
Track the roam — it is strongest where the enemy jungler already is
Dodge the primary — its rotation is one skillshot; sidestep it and the rest is chip
Punish the cooldown — Janna is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 7/10, so a practised player gets more out of it than the average

Methodology
- Data window
- 512,340 games on patch 26.16, Ranked Solo/Duo, NA. Last refreshed 20 Aug 2026.
- Rank aggregation
- Emerald+ and above, pooled. Splitting further leaves samples too small to separate a real effect from noise.
- Role assignment
- A champion is filed under the lanes it actually plays, not the one class it belongs to — which is why several appear in two.
- Counters
- A matchup, not a tier gap: how this champion does into that one specifically, over that pairing’s own games.
- Minimum sample
- The confidence indicator beside every rate is driven by how much of the window this champion appears in. A low reading means read the figure loosely, not that it is wrong.
- Why a build is not a cause
- The best-scoring build is the one the best-placed players happened to take. Correlation is what a rate can show; it is not evidence that buying those items caused the wins.
- Where the numbers come from
- Names, classes, lanes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates are derived samples — Riot publishes none of them, and nothing on this page presents one as measured.
