We were fighting the Giant Spider BOSS in AC… As soon as the BOSS died, I received a poison condition that has no outer(around the icon) nor number indicator of time remaining… I have never seen anything like that before. I guess someone was stepped into the poison field the spider left behind. All conditions I had in the fight was sent to BOSS by Putrid Mark before it died, so I know for sure that the poison was grabbed from others.
That permanent poison have all usual effects. I managed to sent it to those Gravelings, but there were other party members applied poison to them and I lost track. Seems if a new condition apply, it will break the permanent effect and start the time remaining count down.
