Creatures[]
For the spawns in DL, instead of having one spawn for one fixed mob, a certain spawn may spawn one of a couple possible mobs. The spawns are based on mobs within a certain combat level range.
This does NOT mean all mobs within a certain range can spawn; possibly only a small set of mobs are coded for each spawn.
