Guild Wars 2

So basicly speaking about Exotic Armor here, we have 6 Peaces with the Same Runes,
if i get on all of them the same Runes, do it multiply EVERY Rune Stat with 6?

Or do i just get the 6 Basics Stats once?

If anyone out there has some Armor with at least 3 of the same Runes,
they could try equip and unequip one and see how the Stats change.

(I dont so i need to ask) ^^

Rune bonuses are additive, which means they add up between them but only once.
Example: Rune of X, Lets say you have all these runes of the same type X.
Bonuses:
(1) +10 Power
(2) + 10 Vitality
(3) + 20 Power
(4) + 50 Vitality
(5) +15% Burning Duration
(6) + 100 Power

You will get a total of:
Power: 10+20+100 = 130
Vitality: 10+50 = 60
+15% Burning Duraiton.

Same thing if you add runes that have only stats and are not part of a rune set like +14precision +14power +12vitality.

Also equipping 3 of the same runes with only 2 bonuses listed will make the 3rd rune obsolete. For example:

Rune of X:
(1) +10 power
(2) + 10 vitality

Equipping 3 of those runes will give you 10 power and 10 vitality. However, equipping a different rune with a different name will give you the first bonus of that rune again.

For example 2 runes of X:
(1) +10 power
(2) + 10 vitality

And 1 rune of Y:
(1) +10 power
(2) +5% bleed duration

This will give you in total +20 power and +10 vitality.
