On Kassadin, after casting Nether Blade (W), **the passive no longer works until the ability is off cooldown**.
I first discovered this bug in ARAM, then tested it in practice tool. I did not see this change documented anywhere so I am assuming it's a bug.
Please see attached link for a demonstration of the bug.
