To catch a shiny Gastly, there are three things you can try. First off, you can try catching a shiny Gastly in the wild. However, there is a 1 in 8192 chance of encountering a shiny Gastly and may take you hours to find one. Second, you can try breeding a shiny Gastly. There is a greater chance to find a shiny Gastly by breeding, but it still takes a few hours depending on how well you breed. Last, you can use your PokeRadar to chain Gastly. Depending on your luck and how well you chain, you can find a shiny Gastly within minutes or more. If your chain of Gastly reach up to 40 or more, your chance of finding a shiny patch is 1 in 200. A shiny patch will contain a shiny Gastly. You may even find several shiny Gastly from chaining. If you're really lucky, you can get a shiny Gastly from your first or second or even tenth chain.
