Guild Wars 2

Editing the first post for visibility; originally I thought this was a bug specific to the fiery greatsword but after ExTribble’s post about being unable to reproduce it i started testing some more to try to figure out what was happening. As it turns out the issue is with the combination of sigil of fire (and presumably any other sigil with the same functionality) in combination with conjured weapons.
The game appears to be treating the sigil proc as if that was one of the skills from your conjured weapon and consuming a weapon charge whenever that happens. After some testing this seems to be the case for all conjured weapons – shield, axe, bow, hammer, and greatsword.

You can see an example here each time sigil of fire is triggered i lose a weapon charge immediately and another when the attack which triggered it ends.

That actually would be a way to somewhat balance FGS – make fiery rush consume more charges if nothing is targeted. Wondering if what you described is a bug or something that accidentally leaked from test servers.

I just spent a solid 30 mins trying to reproduce this bug and I absolutely cannot. I tried in combat and out of combat, using skills in quick succession, both interrupting prior activated skills and not, and still did not see what you describe.

The only time the charges appear to be used at the beginning and end of a cast is if another skill was mid-use, even for a fraction of a second. Charges are only consumed at the end of a skill activation. Even if you aren’t auto-attacking, any skill that targets your selected enemy (i.e. Fiery Rush) will trigger the autoattack to begin, which explains how you went from 4 charges down to 1 in your example (Fiery Rush+Autoattack for a fraction of a second+Whirl = 3 charges).

If you Ctrl+Rightclick (disable) your Auto-attack you won’t ever see this happen since that disables the functionality where it starts after a targeted skill even if you don’t press 1. This seems to be what’s causing your problem.

Bumping, figured out what was causing the issue so edited the first post with new info and deleted old posts.

So that was the problem at least on my end, I wasn’t using a weapon with on-crit sigils :P Good catch!

I just tested it with a sigil of strength and this time I was able to reproduce it just like you did. I only tested the frost bow and FGS, but since you tested the others it’s safe to agree that it affects all conjures with on-crit sigils.

This is a serious bug, especially for those conjures you usually try to use all the charges on (like FGS). With some on-crit sigils having as low as 2 sec cooldowns, you could potentially lose 3 charges during a single Flame Wave (FGS #1) cast. That’s seriously broken :/
