Guild Wars 2

Do the sigil of night and sigil of force stack?

yes,

/15 sigils

( Force and Force wont stack. Night and NIght wont stack, but say… Night and a “slaying” sigil will. such as Force and Undead for Arah )

So sigil of night falls under conditional category, whereas force is permanent?

Using two of the exact same sigils doesnt stack. Using two different damage modifiers does stack. Obviously night only gives the bonus when the instance is night though. You can have two conditional stacking sigils working together (night + nightmare court for example).

Yep, but there are more nighttime dungeons than daytime ones, so it’s not really an issue.

more or less.

just depends on how much you are looking to min/max

General Rule of thumb would be to have a weapon with sigil of force. Then have another Slot/Weapon with a specific use. Being Either a Slaying Sigil. or Night SIgil.

Just look at All of the Content you are doing and then Determine what would be the most effective for your routine and your budget.

ohh and Dont Forget Food and Potions

Ok, thanks for the input everyone
