Guild Wars 2

So I’ve been testing with Arcane Power and on-crit sigils specifically Sigil of Fire and Air. I’ve discovered what I think is a bug when you have Arcane Power activated and the effect of sigil of Air/Fire procs so I’d like to know if it’s actually working as intended.

So what I know:
• Arcane Power will make your next 5 attacks be critical hits.
• Sigil of Fire’s Flame Blast cannot crit as per the official GW2 wiki page.
• Nothing is mentioned in Sigil of Air’s wiki page if it can crit or not.

What Happened:
• Flame Blast and Lightning Strike has a chance to land critical hits (not always)
• 2 charges of Arcane Power is used regardless if Flame Blast or Lightning Strike crits.

Scenario 1:
I use Dragon’s Tooth with Arcane Power Activated against Indestructible Golem.
Dragon’s Tooth crits for 3,997 damage.
Flame Blast hits for 620 damage.
2 charges of Arcane Power is used

Scenario 2:
I use Dragon’s Tooth with Arcane Power Activated against Indestructible Golem.
Dragon’s Tooth crits for 3,490 damage.
Flame blast crits for 1,107 damage.
2 charges of Arcane Power is used

Regardless if Flame Blast and Lightning Strike are intended to be able to crit when using Arcane Power, I think it’s unfair that 2 charges are used up if they don’t crit.

it doesn’t say if theres an internal cool down does it?

Which one? Sigil of Air and Fire have 5s ICD. Arcane Power will crit for your next 5 attacks including fire trails from Burning Speed and FGS.

This is similar to something that’s come up regarding Stone Heart (new GM Earth Ele trait which makes you immune to crits while in Earth Attunement).

The trait will most likely multiply crit chance of the incoming attack by 0, so that attacks with 100% crit chance (like the Thief’s stealth attacks while traited with Hidden Killer) still function, and just don’t crit.

It’s likely that the sigils are also using up a charge of AP, to increase their crit chance to 100%, which is cancelled out during the roll for crit by the 0% base chance of the sigil effects.

Whether this is intentional or just an unintended consequence, I don’t know - and whether it’ll be seen as something that needs changed is unlikley.

Actually, I’m kind of guessing that the same problem might occur on the revamped Sigil of Intelligence since it works the same way as AP.
