Guild Wars 2

Hey there.

I was wondering about the achiefment: The Bifrost III: The Legend.
This achiefment contains a part where one must be getting hit by a skill called ‘Imprisonment Crystals’ from the Shatterer.
I’ve been trying for some time to get hit by this skill, but it’s just not happening.
It seems that the Shatterer is not immune to blind and that his skill only targets 5 people. In this way, looking at the amount of people attending to the shatterer, the change of being struck by his skill is enormous small.
I was wondering, is it just my fault for not getting hit? or is it a slight problem that will be patched or something?

I’m looking forward for a
thank you very much.

yours sincerely

Did you ever figure this out? I have been caught in the crystals twice now and have yet to get the achieve.
