Varying Monster Spawn

A Shared Spawn is one that spawns [{Creatures]] from a predefined set of more than one creature, as opposed to traditional spawns that only ever spawn a specific creature. For example, a shared Dawnport spawn may select from a set {Troll-Trained Salamander, Mountain Troll}; that is, each time a creature spawns, the type of creature is chosen from this set. This creates a more dynamic environment, because a particular strategy may not apply depending on which creatures were selected to spawn in shared spawns.
