Pack
A Pack Monster or Minion is a Monster that naturally spawns as a part of a Monster Pack in areas or from mechanics like Strongboxes.

Modifiers to Pack Size also provide a chance that there is an Additional Rare Monster in the Pack.

Monsters summoned or created by other Monsters do not count as Pack Monsters or Minions.
