How do the Aflicted assassins have spell breaker on them

Sometimes when im playing as my elemantalist my spells fail on the aflicted assassins because it says they have spell breaker on them. What is going on? The afflicted monks cat be putting it on because they use ray of judgement right?

spell shield maybe?.... a crappier version of spell breaker.. i dunno just a guess

Uh because the monks can cast spell breaker on the assassins...

That or the NPCs are hacking again, I'll report them to ANet.

No it has nothing to do with spellbreaker They use Shadow Form - enchant. Assassin skill, makes them impossbile to hit with either physical (melee, bows) weapons or spells, but when it end it drops their health to 5% or something.

Sounds like an explanation. Quute funny that the message still mentions Spellbreaker, but not exactly unexpected.
