It's an In-game beep.
Kind of like the sound you get when you hear a ping, but it isn't, it's more of a Dull chime.
It feels like a warning or something i should take notice of, but for life of me, i can't see anything on the minimap, on my procs, on my ability's or anything else. It happens across Multiple champs as well.
I have ZERO idea where it's coming from, and it's seemingly random.
Wth is this? It's driving me insane.
On a non jokey point:
I'm on the boarder of quitting playing for a bit until i can figure it out, cause it's throwing my game off badly and it's annoying as hell.
I had it happen 3 times in quick succession when i was mid lane on lux, I became paranoid about it and eventually backed just "in case". :S
I've also had it happen in BOT only customs where i tried to recreate it. STILL have no idea.
Please can anyone tell me what this is?
