For who don't know what this skill is,
this is a skill that can knock you down for 3s + immob for 2s + apply 15 stacks of vul + remove 2 boons.
In normal situation it has a very obvious tell, also it requires target being marked to knockdown, which make this skill easy to dodge.
But this skill is absolutely broken when paired with rifle.
This is normally used by this combo: go stealth -> binding shadow -> mark (+ get quickness) -> DJ. The trick here is that the delay can allow the mark can be cast AFTER binding shadow is cast, that the knockdown can be effective. The delay of knockdown of this skill is almost perfectly line up with the DJ. For the poor opponent, all you can see before the DJ + binding shadow hit you together is the deadeye mark before the DJ under quickness hits you. There is only 0.33s for you to dodge this combo, which gives you death judgement, knockdown, immob, 15 vul (15% dmg increase) + 5 boons removed (if trickery is used) if you failed to dodge within this 0.33s. Also 3 round burst coming for you if you didn't die.
If you think you have stability, sorry 5 boons are removed under this combo. If you think one stunbreak is good enough to dodge the upcoming 3 round burst, sorry there is also 2s of immob.
This is a very very strong skill once you're hit by this when marked. It is a very strong reason for it to have tell even it is cast under stealth. I think the developer has thought of that so the knockdown effect is only done if you are marked so that the opponent can be aware. But the trick part is the skill can be cast BEFORE the mark is applied and this skill gives completely no tell under stealth.
There should be change to this skill. I am in plat and I can see too many people get one-shot by this combo which gives you only 0.33s to react.
One change should be the skill effect should be seen even the skill is cast under stealth.
Second should be the DE mark has to be applied BEFORE binding shadow is cast for knockdown being effective.
