90 Within a given area in a given game, encounters are differentiated by the
91 "slot" they are in and the state of the game world.
92
93 What the player is doing to get an encounter, such as surfing or walking
94 through tall grass, is called terrain. Each terrain has its own set of
95 encounter slots.
96
97 Within a terrain, slots are defined primarily by rarity. Each slot can
98 also be affected by world conditions; for example, the 20% slot for walking
99 in tall grass is affected by whether a swarm is in effect in that area.
100 "Is there a swarm?" is a condition; "there is a swarm" and "there is not a
101 swarm" are the possible values of this condition.
102
103 A slot (20% walking in grass) and any appropriate world conditions (no
104 swarm) are thus enough to define a specific encounter.
