Roleplaying is when Players and the GM describe the actions of their characters and deliver dialogue. Oftentimes, roleplaying naturally leads into an Action being triggered. The GM will ask the Player to perform a Roll which will determine the outcome of the immediate situation, and then roleplay will continue.
Outside of battle, Pokémon Moves may be much more versatile when not confined to the rules of Battling. See the Move section on the page for Types for some examples of how Moves can influence the environment.
