Zepher's Speed change?
I’m fairly certain that none of the “on-switch” skill work out of combat. As far as I can remember, Zephyr’s Speed never did either.
It’s entirely possible I’m wrong. I just thought I remember it happening outside of combat because I would sometimes use it to mine/harvest faster just because I could.
Though I guess it’s possible I was just getting out of combat or in combat when I did it.
Unlike those other skills, this trait doesn’t specifically mention “in combat”
