Thanks, this info is super useful. Story progression not carrying over isn’t a huge issue to me, so long as you’re allowed to keep playing with the host past where your own game world is. I never liked how dark souls required you to play levels multiple times in a row if you want to keep playing with friends.

These two bits are really nice to see too

When playing online, the host’s game world will reflect their progress in the storyline. As an accompanying player, you won’t advance your own story, but you’ll keep any items, levels, achievements, and currencies you earn during the online session. These will carry over when you return to your own game world.

As a joining player, you have only one life. If you lose it, your body will fall to the ground and you’ll switch to spectator mode. The host has two options for resurrecting you: they can either interact with your fallen body on the spot, risking exposure to enemies as it’s not a quick ritual, or they can do so via a nearby Vestige.
