As Alycia mentioned in her
FAQ Post...
What will the Shiny Rate be?
- Our finalized Shiny Rate has been locked in. The final rate will be 1/20,480, and will feature a pity system.
- The Pity System will decrease the overall rate, as opposed to instantly giving you the shiny. As an example, if you were to encounter 500 Pikachu, the pity system will then start scaling down the overall rate, to where it would become 1/20,230.
- The Pity System works on specific Pokemon. So for example, encountering 500 Pikachu increases the odds to encounter a Shiny Pikachu, but will not affect the odds for a Shiny Pidgey (unless you have encountered Pidgeys).
- Boosts will be available through gameplay and donations.
So, slightly less than the previously discussed PokeMMO rate of 1:30,000. But higher than the original poster described in their post.
