How I Hit Challenger in Korea With Glacial Augment Janna – Quick Tips Inside

By 1minlol
Why is Glacial Augment a good rune?
The rune page isn't displaying correctly, so I’ll briefly summarize it here.

(For a much cleaner, clearer, and more intuitive explanation, I highly recommend watching the video instead:
👉 https://www.youtube.com/@1min-LoL)

Janna’s E cooldown is reduced by 20% when she slows or immobilizes an enemy. That means if you land Q + W, that’s a 40% cooldown refund.

But here’s the crazy part:
When Glacial Augment procs (possibly due to a bug), it adds another 20%, giving you a total of 60% cooldown refund.

It gets even wilder with her ult:
Normally, her R should give 20% CDR on E if it knocks enemies back.
But with Glacial Augment, it drops by 40%, and the glacial field itself seems to give another 20%, totaling 60% again.

This unintended synergy makes Glacial Janna incredibly stable and powerful in both laning and teamfights. It’s honestly broken.

Check it out in action — it’s much easier to understand when you see it:
