Graves's Quickdraw does not activate Spellblade properly

Greetings,

the described bug occured in several games and was tested by me with the Practice Tool. Even though every testing was done in the "Summoners' Rift" map, the bug should occur in the other maps, too.

Description: If you are playing as Graves , with an Item equipped, that has the Passive "Spellblade" (Sheen, Lich Bane, Trinity Force, Trinity Fusion) and you use Quickdraw while you are auto attacking an enemy (so if you cancel your auto hit animation with your [E] ability), the Spellblade passive will not get activated. Neither will the icon appear, that shows the activity of Spellblade, nor will the next auto hit be empowered, nor will the item go on Cooldown. Even if you use Flash first, to cancel your auto attack animation, and then instantly use Quickdraw, the same problem occurs. Using Quickdraw while Graves is reloading after his second auto attack will activate Spellblade as expected.

Reproduction:

Start a Game with Graves. Invest at least one skill point into Quickdraw. Buy at least one of the listed items. Start auto attacking an enemy (ideally a Training Dummy). Now use Quickdraw while Graves is not reloading. (So during the first or second auto attack) Spellblade will not be active. (You can instantly press [S] after using Quickdraw to have a better look at it.)

Unfortunately, I do not have any video material, because I have no idea how to record/edit this. I hope that this comment still is helpful and that the bug will be fixed soon.

Best regards,

Dagobert Doc
