Guild Wars 2

Do the Sigil of Fire and Sigil of Air share the same internal cool down when on a dual wielding set? I’m running a P/P thief and am wondering when I use unload can I proc the sigil of air and sigil of fire simultaneously for better dps. Currently am using Sigil of air on my main hand and sigil of damage on my offhand.

They share the same cooldown.
