How close must party members be to reap shrine effects? Is it based off of in-game yards or "screen" distance (e.g., must be visible on screen)? I never know if party members are close enough to get shrine effects.
playing on my 1920x1080 23" monitor, I've noticed its a tad more than the area I can see on screen. I've missed shrine pickups just barely out of screen shot, so I know it isn't much farther than my line of sight
