So maybe my tests didnt work well. Maybe I did it wrong. But if I’m seeing this correctly, it appears that if you have two veils up they arent working as intended.
Essentially, I was using a PU build that included all stealth sources for my mesmer, including Veil, and Mimic. The idea was I’d pop mimic, then veil, then run a bit and as cloak was failing drop the second veil, then Mass Invis a bit later (running through arah) and to my surprise, my stealth fell rather than being stacked on.
Mesmer’s Temporal Curtain does the same thing, so I suspect the behavior is intended but I wanted to confirm. It doesnt hurt much – I can go veil-mass invis-veil or some other combo instead. I just wanted to find out for sure.
