I just want some techniques and or Items to speed shiny hunting .
To begin shiny hunting, you first need to choose which Pokemon you want to hunt. Whether it's a Wooloo or a Wailord, pick your target then go to the location that mon spawns .
Then you need to keep battling the Pokemon of your choice and either catch them or knock them out. The higher your tally of that specific species you've battled, the more likely it is to be shiny. You can check how many you've battled under the relevant Pokedex entry. If you have shiny charm in key items pocket its better. Read the source for even more info!
Hope I Helped!
