It’s not just velco, it’s -everything-
I’ve sat around with my oracle trying to test how hitboxes in this game work. There are instances where I’m WELL out of range of an attack’s zone of effect and I will still take damage even though I’ve moved to the other side of the boss. It’s super inconsistent, at least for people who aren’t playing with low ping. I’m playing in Telsaia from Australia btw and even though casting/damaging enemies seems fine, me taking damage has always been iffy ever since launch.
