All characters and weapons accumulate "mana" (a magical currency for increasing a character or weapon's abilities) whenever they kill an enemy. This mana can be spent to fuse two characters together, an item into a character, or an item to an item. Fusion increases the level cap of the beneficiary by the level of the consumed item or character. By spending mana, the player can improve equipment percentages (stat bonuses given to characters who equip the item or character) and confine percentages (bonuses to characters confined in the item on the field), and even transfer skills to the beneficiary. In "Phantom Brave", weapons have a much greater effect on a character's stats than their natural affinity. The maximum obtainable character level is 9999.
