>>16249457 >Is the shiny rate higher in the Friend Safari?
The majority of /vp/ thinks that this is true, but there hasn't been a datamine of the X/Y ROMs so nobody can say what the probability is for sure. It appears to be on par with the Masuda Method's probability of 1/1638. In addition, pokemon found in the safari will always have two maxed out IVs and have a chance at having a hidden ability, unlike chaining (see below). It should be noted that you aren't allowed to use the Pokeradar in the friend safari, so chaining isn't an option there.
>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 including legendaries if some poor shmuck who doesn't know their worth falls for it. No hard shiny to normal fish ratios yet, but a rough estimate brings it around 1/200 at maximum probability. It should be noted that the mechanics of shiny fishing aren't entirely understood
>What is chaining?
When using the Pokeradar under extremely certain circumstances, one can increase their probability of encountering a shiny in grass patches. 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. While a faster method than randomly searching in the friend safari, pokemon in the wild are not guaranteed any sort of IVs and will not have their hidden abilities. It should be noted that you cannot use the Pokeradar in the friend safari, but this is made up for by the (supposedly) higher shiny rates in the safari. See the guide in OP for more details.
