I have had a quick look around and can see no one else has noticed but occasionally on my Engi, when I use Elixir U i notice that my Endurance gets completely drained when it was full. I tested it in Lions arch and had no other skills or enemies that could of contributed and i have check my traits and found nothing. I can’t see and reason as to why this would happen but if any one can tell me otherwise, please let me know
Edit: Also this doesn’t always happen, as far as i can tell it is fairly random and inconsistent.
