Pokémon Masters EX is handing out 1,000 free Gems to players as compensation following recent game design changes to Pasio Gym Battles. The reward is meant to address player feedback tied to the updated system, giving everyone a small boost they can put toward scouting or other in-game uses. It is a straightforward make good as the developers continue adjusting the mode, signaling they are paying attention to community response while refining how Pasio Gym Battles work going forward.
