Nidalee can use her q in cougar form while stunned.
After playing a game as riven i noticed that nida can use her q in cougar form while stunned, so i looked around on the internet but didn't find much information about it, all i found was this video. In my case nida activated q before jumping on me but even if she didn't begin her animation on Q before getting stunned it still damaged me
Sorry for the bad english.
