I have a couple of questions regarding this matter.
1. When I am the only player with a mission done and start the final mission, are the other players able to attempt it also? Even if they don't have any missions completed?
2. When I get the Soul of Infinity final mission, I have to resist for x turns in that area in order to succeed but other than players attacking me what hazards am I exposed to? Do I have to face encounters or be forced to explore?
