Appendix:Repel trick

The Repel trick is one that allows the player to find the most powerful Pokémon in an area. To perform it, the player needs several Repels and a Pokémon at a specific level. This trick works in all Generations.

How to use

To perform the trick, the player simply needs any type of Repel and a Pokémon at a specific level, (which is weaker than the target wild Pokémon level). The player needs to know the higher possible level for the Pokémon, thus it would be ideal if he or she had a list of the Pokémon in the area.

This trick is possible because the Repel prevents "weak" wild Pokémon from appearing. In this case, "weak" means a Pokémon at a lower level than the first Pokémon in the Party. This means that if the player has a Pokémon weaker than a particular wild Pokémon, that Pokémon continues to appear whilst the weaker Pokémon will stop appearing.

This trick can be useful for finding a specific Pokémon in an area. It can also be used with Pokémon Luring Methods, such as the use of a White Flute and the Pokémon March broadcast to increase the probability of finding a Pokémon.

Examples

Route 111

Take for example the desert area of the Route 111. The wild Pokémon list in this area is:

Pokémon		Games			Location	Levels	Rate
	Sandshrew	R	S	E	Sand	19-21	35%
	Trapinch	R	S	E	Sand	19-21	35%
	Cacnea	R	S	E	Sand	19-21	20%
	Baltoy	R	S	E	Sand	20-22	10%
	Baltoy	R	S	E	Sand	19-21	20%
	Cacnea	R	S	E	Sand	20-22	10%
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.

In this case, if the player wants to find the most powerful Pokémon possible (a Baltoy in Ruby or Sapphire and a Cacnea in Emerald) he or she simply has to put a Level 22 Pokémon in the front of the party and use a Repel.

Mt. Silver

Another example would be the exterior of Mt. Silver where this trick could be used to find a Rapidash. The wild Pokémon list is:

Pokémon		Games			Location	Levels	Rate
All times
	Ponyta	G	S	C	Grass	42	30%
	Rapidash	G	S	C	Grass	44	10%
	Tangela	G	S	C	Grass	39-41	30%
	Ursaring	G	S	C	Grass	42	20%
	Donphan	G	S	C	Grass	42	20%
Day
	Arbok	G	S	C	Grass	42	20%
	Ponyta	G	S	C	Grass	42	30%
	Rapidash	G	S	C	Grass	44	10%
	Doduo	G	S	C	Grass	41	5%
	Dodrio	G	S	C	Grass	43	5%
Night
	Golbat	G	S	C	Grass	40-44	30%
	Poliwhirl	G	S	C	Grass	42-44	40%
	Sneasel	G	S	C	Grass	38-42	10%
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.

If the player wants to find a Rapidash in the Day, he or she can simply put a Level 44 Pokémon in front of his/her party and use a Repel. Since the only encounterable Pokémon at Level 44 at day time are Rapidash, he or she is certain to find one.

Limitations

This trick cannot be used to find the 'weaker' Pokémon, such as a Larvitar found inside Mt. Silver.

It can also be particularly difficult to find a Pokémon at a specific level to do the trick.
