I was aware that the rules say that npc's share action cards, meaning that if a npc uses a given action card, no other npc can use it again while it is recharging.
Recently I realized that the rules also state that multiple monsters of the same type share the same Aggression, Cunning and Expertise die pool. In particular
"When more than one NPC or monster is present in an encounter,
each type of NPC or monster shares a single allotment of Aggression,
Cunning, and Expertise dice for simplicity – you do not
multiply these values by the number of creatures present."
any idea why is that? or what it represents?
Why the bigger the group of NPC's, the less resourceful are they individuals?
