With that, I have added a new feature to the RPG which should make shiny hunting rare Pokemon slightly easier and more entertaining. The new feature is the Wild Pokemon Encounter Boost system. I will explain this update and how it works in more detail.
While capturing Pokemon on any map you will now find that on the main map select page something similar to this will appear near the top of that page:

Every time you capture a Pokemon, you will either begin a "chain" or add to the already existing chain you have for that specific species of Pokemon. The boost or chain will continue to go up every time you capture that same Pokemon, to a limit of +20%. The chain/boost bonus will be added to that Pokemon's wild encounter rate when searching the maps.
For example:
If Eevee has a 1% encounter rate, and you capture 7 Eevee, it will now have an effective encounter rate of 8%!
This update should add a little bit of fun to shiny hunting as well as make finding those rare and valuable Pokemon a little bit easier.
