So I got this idea for Karma's W while I was trying to sleep :p

So I had this idea that came up to me while I was trying to sleep :p . So why not just get it out of my head.

Karma's W would have a new effect that could be used both defensively or offensively. This skill is inspired by her old W.

Focused Resolve ACTIVE: Karma forms a tether between her and the target enemy champion or monster, dealing them magic damage over 2 seconds at 0.66-second intervals and granting True Sight icon true sight of them for the duration.

MAGIC DAMAGE: 60 / 110 / 160 / 210 / 260 (+ 90% AP)

If the target does not break the tether by moving out of range, they are Root icon rooted for a short time.

ROOT DURATION: 1 / 1.25 / 1.5 / 1.75 / 2

(NEW) Karma can now target an ally champion. While tethered on an ally champion, any movement speed bonus that are already in place will extend that duration during focused resolved for Karma and her ally. (NEW) While tethered on an ennemy champion. Any slow effect that are already in place will extend that duration for the time focused resolve is still on the ennemy champion

Here's how it works.

IF DOING THIS ON AN ALLY

Let's say that Rammus would be activating Powerball and Karma has it tethered, she would also get that movement speed bonus. If Rammus' powerball effect would end BUT that focused resolved effect is still active, it would INCREASE that duration while the tether is still on (up for a maximum of 2 second because that tether lasts for 2 second!)

This DOES NOT increase Rammus's movespeed by an additionnal 140%. It only extend the duration and provides an extra movespeed for Karma.

The opposite can be done. So Karma would shield herself to get that extra 60% movement speed and then teether Rammus. Both will get the extra 60% movespeed for 60% up to a maximum of 3.5 second (1.5 for the shield itself and up to a maximum of 2 second for the tether) Doing this combo would be pretty hard to get the maximum effect. So I expect a 1 second bonus movement speed.

This would be a significant buff for her supporting. Since she could do this to save her allies. She could synergize well with Sivir (her ult), Jinx (her passive) Draven, Twitch...

IF DOING THIS ON AN ENNEMY

Let's say that an ennemy champion got hit by Maokai's sappling toss and the ennemy would be slowed by 50%. If Karma would tether that ennemy while the slow is still active, she would slow the target by 50% for the time that focused resolved is still active. This would allow her to land that root easier and kite more easily.

So you guessed it, this could be either very annoying (Combining this with Zilean's 99% slow or Thresh's ultimate) or either just ok (Combining it the red buff or Lissandra's Ice shard)

Karma could do this by herself by launching an Inner flame or souflare on a target, then she could tether ennemies while the slow effect is still on.

So you can see. Depending on the current effect of slow // movementspeed bonus, this could mean alot for Karma. She could use it offensively to kite and land an easier root. Or she could it defensively, and save her allies and herself by going faster.

Using her ultimate won't change any effect on an ennemy or ally.

Is this too OP? How about we forget the numbers and just look at the concept?
