Guild Wars 2

It seems that the minor sigil of luck is not working as of the recent patch. It is supposed to give +.2% magic find per kill, up to 25 stacks, ending on down. Previously, an icon displayed showing how many stacks of this boon were present on the character. As of today, there is not one regardless of how many kills I achieve.

A second sigil from my water weapon, giving +5 condition damage per kill, seems to be working.

Update: I had a hunch, so I allowed a mob to down me to clear the condition damage boon from some previous water combat, and upon getting up and killing the mob, I can now stack the luck.

Therefore, it seems that one of two things are happening. Either

A) Only one boon icon is being displayed, but both sigils are applying their benefits.

or

B) Only one such sigil can apply its effect at any time, and the first to apply gets it until it is cleared.

Confirmed. I encountered the same bug and did the same as you did. Once I was dead and my precision stacks fell off, I was able to see the luck icon.

You can only have stacks from one of the stacking sigils at a time.

Pie Formation.8196:

You can only have stacks from one of the stacking sigils at a time.

In that case, I’d like to be informed about this before I purchase my upgrades; i.e. in the form of an in-game tooltip explanation or something. Nobody has to go on a hunt for information online to dig up some basic information like this. I’m beginning to get real tired of it.
