Sigil of Air does not work in PvE
I can, at least, confirm that the sigil does work in general, in PvE. I happened to put a couple on a temp char today (on staff and hammer) and they’ve been proccing about as expected given the char’s ~35% crit rate. Of course, you could have come across a deeper, situational bug related to your various build details and/or weapon choice(s).
It seems like i was wrong about the sigil. It is triggering properly, just the animation is missing which isn’t a big deal to me. Damage is dealt properly and even the sound effect is working.
I had a sigil of air on a pistol that stopped working for weeks. Finally I put in a new sigil and now it works fine. The cost is not a huge issue for me because air sigils are cheap.
However, I wonder about the other sigils where the effects are not so obvious: there is no easy way to confirm if they are working or not. For example, crit chance and force sigils can only be tested with extensive testing and parsing of logs.
