Volatile Reversal takes you down to low health

I’ve been playing a Void Knight for a bit today and I was doing the arena when I begun noticing that I sometimes went really low. I thought I might’ve just been unlucky going back to a hit in the face and dying from that, but in between two waves were you have to activate the next wave I crafted some gear and used the ability and it took me down to 1%. After running around not being able to make it happen again it suddenly happend once more. I’ve no reliable way to recreate the bug, but it sometimes seem like it just brings you down to minimum health even if you’ve been maximum health for quite some time.
I am not running the Volatile Travel node for reference.
