Interesting, so you made instances differently from the other game. Wait, does that mean that if a full party finds an idol shrine in a map, each player gets to use it?
Well no but kinda? Only one person gets to "use" it but it will spew out items individually for everyone at the same time.
So everyone gets their own idol shrine that triggers when any one person in the party uses it.
And, if someone uses one before you get into the zone, the items will be waiting on the ground for you. Not sure if this is intended or a bug but it's really nice. It actually happened to me today and I was very grateful.
