>>35041291Oh, that's simple. There are two main ways to Shiny hunt: full-odds and methods.
In full-odds, you just encounter Pokémon until something shines. There is a 1/8192 (Gens 2-5) or 1/4096 chance of you getting a Shiny in each of these encounters.
The second way to find a Shiny is through methods. These are features implemented into the game to make finding Shiny Pokémon a little easier. This includes breeding two Pokémon from different regions (Masuda method) and SOS chaining. Also, the key to lasting long in SOS battles is to have Leppa Berries so that you don't run out of PP while also making sure the opposing Pokémon doesn't run out of PP. Hope I answered all your questions, ask away if you need to know anything else.
