* If you charge all 4 levels of your gauge and release, you send them a boss battle to sweat out. * If you charge 2 or 3 levels of your gauge and release, you will use a Spell Card on your opponent's side of the field! Doing this costs the level you charged to minus one. > You cannot use a Charge Attack if you've got less than one full level on your gauge, but the only way to make that happen is by using a Bomb see below. > Using a Charge Attack does not deplete your Gauge, so you can use them all you like. * If you charge 1 level of your gauge and release, your character performs a Charge Attack against enemies on your own side of the field that is more powerful than their regular bullets - most even have special properties (for example, Reimu's amulets will home, and Youmu's sword can destroy bullets). * Your Battle Gauge holds up to 4 levels (and it will alert you when it's hit a new level you can use). Dying will also extend your gauge one or more levels. * Extend your Battle Gauge by defeating enemies and grazing bullets.

However, that isn't enough to send any attacks to your opponent's side (although it is enough to help deal with enemies on your own side see below). * You start each match with 1 full level on your Battle Gauge. This way, the button is exclusive to charging your Battle Gauge attacks. * Slow Mode: You can hold to fire continuously, and it will also both slow you down and display your Scope. This mode exists to allow you to hold to slow yourself down and display your Scope. * Charge Mode: You must tap repeatedly to fire, because holding it charges your Battle Gauge attacks. One look at the Options screen and you'll discover there are two different settings offered for the functionality of your Focus button.
