>>15436032>How do I fish for shiny mons?See the GFShinyGuide link in OP. While far easier to find and catch than with the other methods, the pool of available pokemon attainable from fishing is small, and because they much easier to catch, they aren't valued as high as other non-fishable shiny pokemon. Don't fret, you can usually throw a fishing shiny up on the GTS and get most any non-shiny pokemon for it. No hard shiny:normal fish ratios yet, but a rough estimate brings it around 1/200 on average at maximum probability.
>What is chaining?When using the Pokeradar under extremely certain circumstances, one can increase their probability of encountering a shiny in grass. This is the more tricky method of the three, as it requires that you follow certain rules in order not to break your "chain" or "streak". The higher your chain, the more likely it is that you'll encounter a shiny. See the guide in OP for more details.
