Guild Wars 2

I’m using the whole 6 pack of Superior Rune of Lyssa and it works only on land.
It doesn’t work underwater!
Is it supposed to be this way? or is it a bug?

I believe you need an EXTRA one for your breathing mask because it replaces your helmet underwater!

Same happened to me with the soldier runes.

So yeah, get an extra rune and stick it on your breather.
