Myself and a group of friends that regularly do the raid decided to try and get the Flawless Raider achievement. After a couple fails, one being a lapse in concentration for one of us (not naming names but his GT starts with a K...) in the jumping challenge we made it to Atheon. While fighting Atheon we had a player Pineappled which left us with one less person to kill the oracles. This caught us by surprise and we were killed by the Oracles. The very next run we had just defeated the Templar (again without any deaths) and while jumping down towards the Gorgons Labyrinth two of our players were marked, we continued on thinking that they may have the mark removed when we pass into a loading area, but instead they simply died randomly after being marked for 3 or 4 minutes while moving from the Templar to the end of the Labyrinth. Here is the video proving the mark. Plus some action I got while at the tower and was capturing the clips. Also the Gorgons tried to f*ck with us so we killed 5 of them. The team was; OmikroN TheMonoChroma Sppitt KingPin113 SHIFTY time FusionOfRage
