Question about Armor Bonuses

Sorry but this has always confused me, and it probably is a very nooby question. I already know that you need only 1 Knights/Ascalon absorption peice for it to affect the whole armor, but what about the extra bonuses from other armor for other proffessions?

Like for a Monk, if I get 1 peice of wanderers and the rest of the armor is tatoos, will the +5 vs. ele bonus from the Wanderer armor affect the whole armor, or just that one peice? I am asking this because I am getting FoW armor for my Assassin, and I am going to craft Valkryie armor (HP bonus), but will craft one peice of nightstalker armor (+15 amr while attacking). Will the Nightstalker armor bonus affect the whole armor? Or do I need to craft a whole set of Nightstalker armor for it to affect the whole armor?

The only armors that provide a global effect are Knight's/Ascalon, and Mesmer's Courtly(?, whichever one it is that gives armor while casting).

no. the bonus from everything except knights/ascalons/mes courtly, is per piece, not universal.

And yes. it is courtly.

I'm not familiar with the new armor mods, but if the mesmer +15 while casting is global then the assassin +15 while attacking should be as well. How else could it function? The +armor is per piece since the damage hits a particular piece. Those types of mods are not tied to a piece.

Alright so +15 armor "WHILE" bonuses are global (while in a stance/while under a weapon spell)? Or is that pure speculation and have yet to be proved for the new faction armor? I really need to confirm this.

Only the +15 while casting. All the other "while" bonuses are local.

No, it doesn't make sense. Deal with it. :P

ok well what about the rit armor u get+5 ar for 1 spirit +5 for 2 and +5 for 3
now with 3 spirits u would have 15 armor bonus? thats the first question second is -is that 15 armor over all or just that 1 piece of armor cause it would seem universal.
