Equips a Unique Weapon. It will be unequipped when MP is fully depleted or all bullets have been fired.
When the Unique Weapon is equipped, Notes activates, allowing the use of skills.
Notes can be hit through shooting and skill use. If the skill button is not pressed at the right time, the skill will fail to activate.
Failing to hit Notes through shooting significantly decreases MP.
Successfully hitting Notes grants Perfect Pitch. Perfect Pitch decreases when a note is missed or incorrectly entered.
