Rarity Tiers

When discussing finding Pokémon in the Wild, Pokémon World Online does not use a labelling system to determine which Pokémon are easiest or hardest to find. Instead, we use a "Tier" system, where Pokémon are rated based on the average amount of time a player is expected to extend to encounter a Pokémon.

Key to spawn rates:

Tier 1, marked as #1 - Easiest to find, will appear in under 20 minutes on average.

Tier 2, marked as #2 - Slightly more difficult. Should appear on average, 20 minutes to 1 hour apart.

Tier 3, marked as #3 - 1 to 5 hours average time between spawns.

Tier 4, marked as #4 - 5 to 15 hours average time between spawns.

Tier 5, marked as #5 - Anything over 15 hours average time between spawns.

Explanation

The time estimates given for each Tier represent the average amount of time a person would have to invest to find a Pokémon of that tier in a given area. This does not mean that a Pokémon listed as "in one hour" will be found in one hour, nor does it mean you always have to wait one hour to find another. What it means is, if you spend one hour in this map (and it doesn't have to be all at once), you will on average see at least one of this Pokémon.

A better way to think of it is: If a Pokémon is listed as appearing "once per hour", and another "once per day", you are about 24x as likely to find the first than the second at any given time. Of course, luck plays a factor too, so maybe you might find the rarer Pokémon first sometimes, or maybe it might take a little longer to find one. Treat these guides as estimates only.

Example

Butterfree is set to take an average of 7 minutes to find in Johto's Hidden Crag. This means on AVERAGE butterfree should show up every 7 minutes, however it is still based on luck - so you might find 3 in a row, or go 30 minutes between sightings. The same goes for whether the average time is 7 minutes, 7 hours or 27 hours. Luck is always a factor, we just provide averages to give you an idea of what to expect.
