So Originally i entered the path of blood and noticed i could not do a thing without dying, noting that the door is locked behind me i teleported out via waypoint and went about my way. Few hours later i completed everything in Arx but the path of blood, so i went to do that; lo and behold the door was locked and no about me attacking, lockpicking, or talking to the priest would open it. I tried various tricks like putting the teleport pyramid right by the door and putting barrels around it in hopes one of my characters would clip or teleport behind the door...but nothing....i would reload before the path of blood got bugged..but that is almost a days worth of work id rather not redo. Cheers.
