Cooldown is for dart 12 seconds, stun lasts for 5.5 seconds if the enemy does not take damage

also fun fact it looks like every time you shoot a teamie to heal for the base healing damage you get 7% ult

I'm not totally positive which is why I put it in tentatively, hopefully it isn't 2x.

If you click the ult button it shows her ulting a Rein and he walks through those low health characters one swing each (dunno if Zen was buffed during that) but in the gameplay trailer she also ults a Rein and he plows through a Junkrat, Hanzo, and Zarya one hit each too.

Not totally positive as of yet what it actually is.

edit: nvm i misunderstood what you said, pm an admin about it

Yeah like I was discussing with my friends about this it seems like her ult is meant to be synergized with a dps player's ult.

It appears the damage boost it gives is 100% (double damage) and the damage reduction it gives the recipient is 50%. If you were to tag that on say a Soldier's ult it could absolutely TEAR if the other team didn't have a Rein sitting around and it would instantly devastate a team if you were to give it to a Reaper when they ult.

You possibly also tag it on a Winston so they can jump in and sac for the enemy Mercy. With the damage amp + damage reduction combined with his large health pool it could be effective.

edit: Her damage buff from the ult only grants the recipient 50% damage.
