Roaming Pokémon

Once players come upon the following Pokémon in stationary Set Encounters, they become Roaming Pokémon and wander around the whole region of Roria, with an extremely slim chance of being encountered.

This particular type of encounter is exclusive to Legendary, Mythical and 2 individual Event Pokémon.

Mechanics
In core series games, Roaming Pokémon had two notorious habits: they would constantly teleport from route to route and also immediately try to flee when encountered - keeping their health and status conditions if they were damaged before successfully retreating.

However, in MythWorld, regular Roaming Pokémon have an encounter rate of 1/1000 (0.1%) and are generally found in all locations with grass and flower patches - as well as walking encounters inside caves, etc. (unlike in core games, where this would rarely lead to Roaming Pokémon showing up.)

Roaming Pokémon will also battle the player, instead of attempting to escape in the first turn, in sharp contrast to their behaviour in the core series, unless encountered in Roria Safari Zone (which is not in game as yet).

At the moment, all regular Roaming Pokémon appear at Lv. 40, while the levels of Roaming Event Pokémon are not fixed — they are in the level range of the route they are found in.

''*Warning: If encountered in the tall grass or flowers in Roria Safari Zone, the Roaming Pokémon will abide to Safari Game mode instead of battling against the player. This also means that it has a chance to flee in each turn.''

Roaming Pokémon are not "One chance only" encounters — if the player is very lucky they can encounter the same Roaming Pokémon multiple times, even if it has already been captured - or encountered and not captured.

As a result of this, status conditions do not remain on Roaming Pokémon if the player fails to catch them. Nevertheless, with the general rarity being 0.1% and specific encounter rate further divided, players are still strongly recommended to save immediately after successfully catching a Roaming Pokémon.

Turning off Autosave, and manually saving the game before actively hunting for one, is also recommended to preserve Poké Balls, in case the attempt at capture ends up as a failure.

Game Pass and Ro-Power
An Ro-Power for quadrupling the Roaming Pokémon encounter rate is listed on the Ro-Powers tab of the game menu, as being available. As with all Ro-Powers, it is not possible to purchase these at the moment.

In the original PBB this Ro-Power only became available after the player had activated three or more Roaming Pokémon encounters. As well as this, a permanent game pass for doubling the chance of Roaming Pokémon encounters was also available for 600 Robux. These two boosts could stack with each other, bringing the maximum encounter rate to 1/125 (0.8%). Unfortunately they did not work on Event Roaming Pokémon.

As all Game Passes are included free at the start of MythWorld, it is unknown whether the Roaming pass will ever be made available in game.

Master Balls
Master Balls can be bought in Poké Ball Emporium, Anthian City - Shopping District.

These ultimate Poké Balls are guaranteed to catch any Wild Pokémon and cost 300,000 Pokedollars each. They cannot purchased in bulk, disabling the Premier Ball bonus.

Alternatives to Master Balls
Players who do not have enough Pokedollars can buy Quick Balls and use them immediately when a Roaming Pokémon shows up. Quick Balls have a 5× catch rate when used in the first turn.

If the Quick Balls fail, then Dusk Balls are the best option when players are battling Roaming Pokémon overnight or in caves as they have a 3.5× catch rate.

Elemental Balls were included in PBB. These used the Roaming Pokémon's type to players' advantage, but they cost twice as much as Quick and Dusk Balls, while only having the catch rate of a maximum effect Dusk Ball. The Elemental Ball is not yet included in MythWorld.

Weaken + Status Condition
As Roaming Pokémon do not flee on the first turn, players can simply apply the same strategy for catching Set Encounter Legendary or Mythical Pokémon.

Start by throwing a Quick Ball (5× catch rate) in the first turn.

If it fails, weaken the Pokémon with attacks that will not make it faint, until its health bar is in red. is a commonly used attack for catching Legendary and Mythical Pokémon because it is a unique attack that always leaves opponents with 1HP. The TM54 False Swipe is available for purchase in the BP Shop, Colosseum Marketplace for 45 BP, while some Pokémon also learn this move via. (Scyther, Axew, etc)

Inflicting a status condition can also increase the catch rate, but players are strongly discouraged from burning or poisoning the Pokémon in order to prevent potential knockouts. Once the Pokémon is in critical health and is asleep, paralysed, hypnotised or frozen, then use the most effective Poké Balls, according to the situation, until it is caught.

Repel Trick
The was widely in core series games to find Roaming Pokémon.

Bottles of Repel, Super Repel and Max Repel, when used, shut down all Wild Pokémon encounters below the level of the player's leading Pokémon. Therefore many players used this trick to track down Roaming Pokémon, which were almost guaranteed to be stronger than normal Wild Pokémon in those games.

However, as in the original PBB, this is disabled in MythWorld as it would allow players to encounter Roaming Pokémon far too easily and efficiently, nullifying the 1/1000 encounter rate.

Regular Roaming Pokémon
All regular Roaming Pokémon have a combined encounter rate of 1/1000 (0.1%) and can be boosted by the game pass, as well as the Ro-Power. Their levels are always at Lv. 40. Once they show up, the music immediately changes to the Legendary and Mythical Pokémon battle theme when the screen flashes white.

Default Roaming Pokémon
The Pokémon listed below can only be encountered as Roaming Pokémon. Set Encounters are not available for them. To trigger their Roaming encounters, players must first visit a certain location. The first 7 roamed in core series Pokémon games as well, until Regigigas, who broke this pattern.

Roaming after Set Encounters
The following Pokémon can be found roaming around Roria after being battled in their Set Encounters, regardless of the result. Due to their extreme rarity, players should focus on catching these Pokémon during their Set Encounters, rather than expecting to find them easily in Roaming battles.

Event Roaming Pokémon
In the original PBB, the following Pokémon roamed around Roria during certain events. Their encounter rates were slightly higher than the afore-mentioned regular Roaming Pokémon, but they were still extremely rare to find. Their levels were also not fixed. Ro-Power and the game pass would fail on these Pokémon. The background music would only be the normal Wild Pokémon battle theme when they appeared.

Scale of Roaming Pokémon
Among all Regular Roaming Pokémon, within that 0.1% encounter rate, there is a hidden scale to determine how scarcely will a specific Roaming Pokémon show up. The scale runs from 2 to 4, with 2 being the lowest. A pattern can also be found in the scale, as follows:

Trivia

 * The encounter rate of White Haunter was 1/800 (0.125%) at first. A few days prior to the 2016 Halloween Event's end, the rate was increased to 1/500 (0.2%).
 * In the original PBB, the Ro-Power to increase the roaming encounter rate was the most expensive, at 150 Robux. The permanent Game Pass cost 600 Robux.
