So... I just played vs a Twitch Taric botlane.
Apparently, Taric's E is longer than Twitch's reveal range, and while Twitch is stealthed the dazzle ray is **invisible**.
Why? I mean, I've got stunned and I didn't even know why until Twitch came out of nowhere and melted me.
I don't know if this works with other champions too, but it makes no sense that I get stunned by something that I don't even get to see before dying.
