A question about Perilous Wilds Follower rules — I see that followers operate like monsters with their own damage and hit points. I can figure out how that works in combat.
But what about a follower with the “Group” tag? Do they function as a single monster in combat? Is the whole group eliminated when their hit points are gone? What about damage? Do they roll only their die — or is there an addition of +1 for each member of the group after the first?
