Every player and weapon has a base energy capacity. Energy is used when players enter into tournaments, contests, and leagues - or when a weapon is used to apply a boost, augmentation, or enhancement.
Different actions require different amounts of energy. When energy is depleted, players have to replenish that energy before entering into a new tournament, game, contests - or to utilize a weapon’s boost, augmentation, or enhancement.
A player’s tier, level, attributes, avatar traits/accessories, and proven skill level all have varying impacts on the amount of energy depleted by performing a specific task.
