In the Pokémon world, there is no creature rarer than the Chromatic Pokémon (or Pokémon Shiny). On paper, they are Pokémon like any other in terms of their statistics or their skills, but they have a peculiarity: they have a different color. When a fight is launched, there is about 1 chance out of 4000 that the Pokémon you are going to face is chromatic, hence their rarity. There are however methods to force luck and increase your chances of getting Chromatic Pokémon. In Pokémon Sun Rom, Pokeradar or hordes will not be abused, but the SOS system and its combos.
In pokemon sun rom, injured wild Pokémon can call for help from other Pokémon. There is no limit to the number of calls for help a Pokémon can make, but there can be no more than 2 wild Pokémon at a time. What to know is that for each Pokémon beaten in a fight, the chances that the next invoked Pokémon is Chromatic increase. You will have understood that you will have to fight your fight against wild Pokémon as long as possible and beat as many Pokémon as possible without ever putting the two Pokémon opponents at the same time in order to be able to cross a Chromatic Pokémon.
One could say that it is enough to hurt a Pokémon and to eliminate all the other Pokémon that help him, but there are in fact various problems that make this strategy complicated. When you hunt Chromatics, you are actually playing against time! First of all, chasing the Chromatic Pokémon is fairly simple against very low-level creatures, but if you come to the idea of hunting Chromatic Pokémon like Goupix, you only find in the wild At level 45, you will have to take a lot of damage without dying to preserve your SOS battle chain.
In addition, eliminating Pokémon on the chain is fine, but it will inevitably come at a time when you will lack PP (Point Powers) and where you will not be able to beat the Pokémon that will stand against you. The same goes for wild Pokémon who may fall short of PP and commit suicide with Fight if you are not vigilant! Attacks such as Explosion, Aries, Boutefeu or any other attacks that cause the Pokémon to hurt, and can kill itself, can also put an end to your ambitions. Finally, it would be too easy to take advantage of the state alterations to keep a Pokémon alive without spending its PP or PV.
Only, a Pokémon that has undergone a state alteration (such as Sleep, Paralyze or Poison) can not call for help! It will therefore be necessary to maintain the opponent to handicap him, but not too much. We will therefore establish a strategy to maximize its chances of capturing Chromatic Pokémon in Sun Rom by taking these constraints into account.
First of all, you will need objects. Tons of objects. To compensate for your loss of PV or PP, buy several hundred Potions and Reminders to keep your Pokémon alive. Since it is not possible to buy Oil in the game, you will have to farm Mepo Bay to recover PPs in full battle. You will also have to buy Orbs Frousse. These increase the chance of a Wild Pokémon calling for help. It is enough to use one per combat.
