Question about Assassin armor

I have read on Guild Wiki that Nightstalkers armor, each piece gives you +15 armor while attacking. Is that universal for your whole body or just that single piece?

Local. You dont get +60 armor for wearing the whole 4 peice set lol, just +15 to each peice.

Most everything is local, few exceptions. Namely Knights/Ascalon armor on warriors that is thought to be "bugged" because it is global.

Yea i kno it wasnt +60 armor, i was just asking if it was universal because warrior ascalon gives -2 dmg reduction on all pieces, so i might have this this was an effect on all assassin pieces.

Ascalon/Knight's armor is the exception, not the norm.

Ascalon/Knight's armor is thought to be bugged. In other languages the translation on the armor peices imply that the dmg reduction is local, which is what you'd think because thats how its "supposed" to be (If it was meant to be global, they wouldnt have put it was local on the armor in other langauges, and it being global makes buying full ascalon/knight useless).

Even Gaile Gray said not long ago in her "Feedback Sought" threads that she'd check if it was a bug/glitch or just a design flaw.

Don't get your hopes up. The issue has been present since the original Guild Wars release, and several times they have claimed to have fixed it. They haven't.
