Guild Wars 2

so ive decided to have a seperate set of weapons just for dungeons, that can constanly rotate sigils since theyre cheap anyway. My question is this… will a superior dungeon sigil (10% damage to whatever) and a superior force rune stack?

Yep.

From the GW2 wiki notes on sigils:
“Charging and non charging sigils can be stacked.”

its not a charging sigil though. its 10 more damage to enemies in that dungeon, and a 5 damage in general

… does anyone know?

They work.

It’s like saying “10% longer cripple and 10% longer poison doesn’t stack because they are both [non charging]”
