Guild Wars 2

Apologies if this has been covered, but if it has, my search skills have failed me. I’m going to bed immediately after hitting 80 (finally I can buy weapons I want to keep), and next time I log in, I intend to buy an ascalonian greatsword. My problem is that, in most locations, the sigil of ghost slaying is totally useless, so I want it gone. Before I spend good coin on sigils (gold, silver, copper, whatever), I would like a better understanding of the mechanics of replacing sigils. My assumption is first in/first out, which would mean that if I applied 2 sigils, my sigils would stay and ghost slaying would go away, and if I applied another, I’d keep the 2nd and lose the first. Can anyone confirm/deny/clarify?

First in first out isn’t how it works. You pick your sigil then highlight which position you want it in. you could buy a couple of low lvl blues and minor sigils and practice first just to get the feel of how it works if you think it might help.

When you click to apply the sigil you get a choice of which slot to fill, simple.

Even easier. Thank you.
