# Group
Certain monsters have a tendency to appear in groups. Due to this, they are more common than their monster frequency would imply.
A "large" group consists of 2-11 monsters and a "small" group of 1-4.[1] If more than one monster is generated, the number of additional monsters is divided by 4 for players of level 1 or 2, and halved for players of level 3 or 4, but is always at least one.[2]  Extra monsters are never peaceful.[3]  If a monster created as part of a group would be peaceful, it's skipped; this can effectively reduce the group size for some monsters.

Monsters that appear in large groups
With a 2 in 3 chance, they're generated in groups of 2-11; otherwise, a group size of 2-4 is used.  The average group size is thus 51⁄3.
