Within a given area in a given game, encounters are differentiated by the
- slot they are in and a world condition.
+ "slot" they are in and the state of the game world.
- 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.
+ What the player is doing to get an encounter, such as surfing or walking
+ through tall grass, is called terrain. Each terrain has its own set of
+ encounter slots.
- 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.

+ "Is there a swarm?" is a condition; "there is a swarm" and "there is not a

- A slot (20% walking in grass) and single world condition (NULL, i.e. no
+ A slot (20% walking in grass) and any appropriate world conditions (no
swarm) are thus enough to define a specific encounter.
Well, okay, almost: each slot actually appears twice.
