So sometimes when I play as 
I dominate lol, but when i'm need some MR such as 
or 
her Q stops working. It wont activate it wont do anything. I tried binding and rebinding but still wouldn't work. And this only happens when I purchase these items. Hope im not the only one with this problem.
CaptainWednesday3 votesThe Spectre Cowls weigh Vi down too much.
Chaotic1341 votesIt's Thursday. You're late.
CaptainWednesday2 votesFor a Captain, everyday is a Wednesday.
Chaotic1341 votesIs your nemesis TGIFriday's? Where every day is Friday.
CaptainWednesday3 votesWho or what even is TGI? Is it an acronym? Last time I ate there, the waiter didn't know. Ironically, it's one of my favorite places to eat at :P
Chaotic1341 votesxD I can't tell if you're being sarcastic or serious about that so I'll answer it, anyway. TGI = Thank God It's
CaptainWednesday2 votesTGI Wednesday
RiotLtRandolph2 votesInteresting. I haven't heard of this one, but I'll give it a shot tomorrow to see if I can reproduce it.
TheInferno1231 votesI have a friend who actually has the exact same problem shell buy into spirit visage or banshees veil around mid to late game then her Q will stop working for the rest of the game, perhaps its item perhaps not. Thought only she had the glitch, guess it might be more than just her.
Sir ArmaMalum1 votesThis sounds possibly like it may have a root cause in spectre's cowl, out of curiosity did the Q bug start when she had cowl or only after buying into BV or Visage?
TheInferno1231 votesSome games she finished buying the items and it happens, other games it happens when buying components leading to the items, and rarely (but still happens) she wont buy any of those items. So based on the fact it can happen even without the items and its probably not time based, it might be situational and buying the items was simply coincidence. I'll try to look into it with her and I'll update whenever I can.
RiotLtRandolph2 votesI can't get it to happen on my machine, but I'll keep an eye on this thread and ask around. If anyone has more details or a more reliable way of getting it to happen, let me know.
Carol NaNa1 votesi had the same problem and lost a ranked game because of this
zzman730511 votesive had it happen too around the time i bought some MR, specifically but i noticed that someone else posted something about it http://boards.na.leagueoflegends.com/en/c/champions-gameplay/datPkQVu-vi-and-her-q
i dont know what is causing it for sure, but it is defiantly a problem
TheMaskedGanker1 votesI just played a game as vi we were easily winning i bought iceborn gauntlet
and my q stopped working. Because of that we lost the game.
EliteSerial1 votesThis just happened to me in a Summoner's Rift game, at about the 30 minute mark I was unable to use Vi's Q. I had none of the items listed below.
Kaznar1 votesI don't remember the items I had when it happened to me, but my Q stopped working after I fought with a Morgana. I was trying to double Q to interrupt her ult and from that point forward it refused to work. Rebinding, clicking, nothing. I had to kill the game with task manager and rejoin in order for it to work again, and by that time we were so behind it didn't matter since Vi is pretty worthless without her Q.
SirRancealot1 votesI had this issue one time. I asked in all chat and one of the enemy team said to hit alt q. After doing this it worked fine. Idk if the same thing but just thought I'd put this out there just in case.
Regulus1 votesWhile I do not remember if it happened after I bought a banshee veil, I remember that there was a ranked game where I could not use Q right after respawning and buying something. Only Q though, the rest were available to use.
Liam Neeson1 votesI've had the same issue as well, it seems to happen specifically with spectres cowl.
Kaznar1 votesNot sure if an update has been found on Riot's end, but it does seem to occur when you attempt to charge your Q at the moment you become CC'd. Two cases that have happened to me were Morgana ult and Jinx baby bear traps.
This bug also exists for Varus and his Q.
Killing the client and restarting seems to fix the bug.
A friend informed me that you can self cast the ability in order to use it, but I have not been able to personally test this.
