Ferrum/Technology

Battle AR
A special device embedded with a Synergy Stone, worn as an earpiece by a Battle Trainer. It allows the trainer to sync up with their partner Battle Pokémon, and also project battle information into their field of view.

Battle Capsule
A device that instantly creates the battle arenas in which Ferrum Battles are fought. Once activated the capsule floats in mid-air and creates the battle arena. It is also outfitted with numerous functions that support the holding of these battles.

Battle Arena
The walled-off area inside which Ferrum Battles are held. Created by a battle capsule. Changing the capsule's settings can create arenas of different sizes and shapes.

Virtual Paint
One of the functions of a battle capsule. When two Pokémon of the same species battle, virtual paint is applied to temporarily change the color of one of the combatants, making it easier for spectators to follow the action.
