Guild Wars 2

Hi,

maybe this is a old question but i want to know if the blind inflicts with cloacked in shadow negate the effect of 2nd downed skill of some class (like engi, ranger ecc ecc).

Yes it does.
Too Short.

Not on rangers according to the wiki.

Something is buggy with this skill. I have seen it work both ways. Also strange is that sometimes if 2-3 players go up for the stomp it only effects some of them.

Guardian Wave of Light has a similar issue…. sometimes when they are blinded it misses sometimes it hits and pushes back.
