[GAMEPLAY] Riven's Q With 100% Consistency Fails to Deal Damage

Bug Run-down for Devs

Riven's Q functionality, by which it will attempt to lead a moving target when using her Q while hovering over an enemy, will consistently cause the Q to move in both the complete opposite direction of the mouse and her target, dealing zero damage, even though her Q is supposed to travel in the direction of the target the player is deliberately hovering their mouse over.

Easiest Method of Reproduction in Practice Tool

1. Place a target dummy close to Riven.
2. Knock the target dummy into the air with the 3rd cast of Riven's Q.
3. Cast Q again while the target dummy is airborne and targeting it with your mouse cursor (note this requires the usage of the refresh cooldowns feature.)

Demonstration

Some quick notes on this method of reproduction:

• Riven's Q will move towards where her target dummy is facing, not where it is moving, this is how you can knock the target dummy backwards but be sent in the opposite direction.
• The target dummy will face the direction of your controlled champion when placed, this direction is denoted by the arrow at the base of the target dummy's model.
• This particular method of reproduction does only demonstrate it with an airborne target but it happens due to any kind of movement, not just knockups or Riven's 3rd Q, which I'll demonstrate in other clips.

Some other quick clips for the dev's demonstrating just how destructive and consistent this unintended interaction is:

• Consistency
• Against CS
• Against champions <- both of these Q's missed although cursor was over Jax when the Q was cast.

To keep this discussion productive, I would like to ensure that everyone is as informed as possible on the subject, so I'll spend the rest of this post demonstrating the various behaviours of Riven's Q. I'll try to only describe only the behaviours that may be relevant to this discussion as otherwise I could be here all day.

Riven's Q has two main groups of behaviours, depending on whether or not the player is highlighting a target with her mouse cursor when the ability is cast.

• Riven's 'Untargeted' Q

• Riven will dash the maximum distance of her Q, ignoring all unit collision, in the direction she is facing at the time the ability is cast.
• This behaviour ignores everything other than terrain and the direction she is facing, including all unit collision, even when starting from inside a unit, even when travelling through another unit and even when ending inside another unit.
• Here is a clip demonstrating these behaviours where Riven is initially standing inside the collision box of the a target dummy, travelling through it in the direction she is facing without being directed immediately away, and travelling through a second unit throughout the dash, maintaining the direction she is facing. Example 1.1

• Riven's 'Targeted' Q

• Riven will dash in the direction of the centre of her target, travelling the required distance for Riven and her targets hitbox to make contact, ranging from the minimum dash distance to the maximum, again completely ignoring unit collision.
• Here is a demonstration of the targeted Q redirecting Riven towards her target and travelling the minimum amount as her target is close. Example 2.1
• Here is a demonstration of Riven travelling as much as required to meet the target's hitbox. Example 2.2
• Here is a demonstration of Riven travelling the maximum amount to attempt to meet the target's hitbox. Example 2.3
• Note in all of these examples the direction Riven is initially facing is ignored.
• To demonstration the concept of Riven always at least dashing a minimum distance here is Riven standing close enough to the centre of her target so that the minimum dash carries her to the other side, causing the following Q to travel in the other direction towards where the centre of the target now is. Example 2.4

Everything working as intended, until the target starts moving against a moving target, Riven's targeted Q will instead:

1. Travel, not towards the direction of the centre of her target, but instead towards an area in front of where her target is facing, once again ignoring all unit collision.
2. Here is a demonstration of Riven travelling towards in front of her target instead of towards both it, and the mouse cursor. Example 3.1
3. Here is a demonstration of Riven travelling away from her target as although she is highlighting her target she instead directs herself towards an area in front of the target. Example 3.2.
4. This may look like some kind of collision, it is not. Dashes, blinks, flashes, shunpo's etc, do not initiate any pathing calculations that cause irregularities in the direction champions are facing and Riven's Q when targeted ignores the direction she is facing anyway.\

Please keep discussion civil, objective and constructive. This is a lot of information but because of it, I hope we can all be on the same page in understanding this problem. Thank you for your time.
