Is there any way to leave a dungeon in progress without actually abandoning the duty if your gear drops to zero percent? We had a member of our party recently whose gear broke because it was the first time doing a trial boss for the entire group, so we ended up wiping a few times, because they were unable to find a method to exit the dungeon and had no dark matter on them, they ended up having to abandon duty and eat a 30 minute duty penalty (incidentally this was the first time they EVER abandoned a duty, so I think that is a little severe considering they had no other option, their healing was simply unable to keep up with the damage with so much broken gear.)
