Guild Wars 2

Does the 10s cooldown affect phantasm distortion as well, or only your 3s distortion?

I believe only you.

Only you. Every phant gets his pitiful 1s distortion on summon.

And the trait as it is now will be gone as Soon™ as the new trait system will land in game, so don’t get too used to it :\

Yeah every kill makes you distorted for three seconds and your illusions/clones get one second upon summons. I see invinceable a lot when my berserker changes through someone or after I kill someone and I get attacked.
