Riven Bug, below the Turret and "Invisible" using Q

So, this is a bug that requires riven to use her third q to jump down under the fountain. It does work, but it also can make her "invisible".

How to recreate: use third q, to go under the turret, there are some videos around detailing this. After you are under, you must either use w or ult, followed by a rapid succession of q's. don't click till you are on your third one.

Recreation rate for under turret: 100%, you just have to get it at the right angle. Recreation rate for invisible: 50% on w, 100% on ult.

When you turn "invisible" however, your character just goes off screen. Enemy players can see you, and so can allies. You cannot see yourself, until you move your view off your champ, and bring it back, your character model will be back.

It's not really that big of a deal, but it possibly could lead to problems. Source: I recreated in a game for about a half hour, testing the possibilities. Just ask if you have more questions.
