New Zed Visual Bug?
I found this while messing around with Zed in the practice tool, if you shadow 3 times you'll be able to shadow ontop of yourself and do it continually, which has weird effects on Zed. (Sadly you'll have to try it for yourself to see anything but the invisible shuriken, since my computer refuses to record anything below 5 fps right after I finished making that clip)
It can potentially lock you out of flash if you shadow on top of yourself enough times, and walking breaks the glitch and brings everything back to normal. Pretty neat, though not at all practical. [slayer-jinx-catface]
