  • Added evolution requirements to accommodate for both of the above
  • Added API event for after an evolution finishes
  • Changed showdown gender ratio conversion now that our assets are corrected
  • Moved Shedinja gimmick from the evolution implementation to an event listener, added config option for the gimmick to happen
  • Added basic system to register global species features
