Guild Wars 2

Permanent stat bonus Sigils:
Info: Stat bonus Sigils increase the effectiveness for the skills associated with the weapon the Sigil is on, without further requirement.
Dual Wielding: Two Stat Bonus Sigils have the same effect as one, but on all Weapon skills. Using only one Sigil gives the bonus only to the skills relatet to the weapon the Sigil is on (1-3 for the main hand, 4-5 for the offhand).
List of the Sigils:
- Sigil of Accuracy [increases critical chance by 1% / 3% / 5%]
- Sigil of Force [increases damage by 1% / 3% / 5%]

So My question is what happens when I have this Sigil in my main hand and use a skill that uses both weapons for example Thief dual wield skill Unload. Does the whole skill get 5% more crit or only half the hits, or.. no effect at all?

Ah well since nobody answered, Im gonna answer my own question!

The statement i quoted was from this forum when i searched on sigil of accuracy. I think this statement is wrong, because I just tested this in Heart of the mists and the Sigil of superior force which gives 5% damage, gives 5% damage to all skills no matter what hand it is in, so i think the 5% crit is for all your skills no matter what weapon you put it in.

The crit thing is very hard to test because 4% vs 9% crit is barely noticable.. but putting the 5% damage gave clear proof to this theory. My assumption is that these runes work the same.
