+    Within a given area in a given game, encounters are differentiated by the

+
+    Groups of slots belong to encounter types; these are what the player is
+    doing to get an encounter, such as surfing or walking through tall grass.
+
+    Within an encounter type, slots are defined primarily by rarity.  Each slot
+    can also be affected by a world condition; for example, the 20% slot for
+    walking in tall grass is affected by whether a swarm is in effect in the
+    areas.  "There is a swarm" and "there is not a swarm" are conditions, and
+    together they make a condition group.  However, since "not a swarm" is a
+    base state rather than any sort of new state, it is omitted and instead
+    referred to by a NULL.
+
+    A slot (20% walking in grass) and single world condition (NULL, i.e. no
+    swarm) are thus enough to define a specific encounter.
