Guild Wars 2

I know two matching stat boost sigils, such as two Sigils of Force, don’t stack. Does anyone know if two sigils of slaying, such as Undead Slaying, stack if you have one on each one-handed weapon you are using together?

The rules are simple:

• you can only have one killstack at once
• you lose all stacks on downed or mapchange
• stacks are like buffs and not bound to “wearing the actual weapon”
• using the same stack sigil twice at the same time, will grant you two stacks per kill
• stacks are capped at 25

[ Edit ]

I just realized, that you were talking about a totally different thing.
As I’ve understood the system, those wouldn’t stack either. Just get one sigil of force and a sigil of “xyz slaying” on each hand.

2 identical sigils will NEVER stack
