Dark Impulse (KHBBS)

Dark Impulse (ダークインパルス) is a Level 2 Command Style exclusive to Terra in Kingdom Hearts Birth by Sleep. It is activated by using Zero Gravity-related, Magnet-related, or dark Deck Commands.

Mechanics
While using Dark Impulse, Terra attacks become faster and deal dark damage. The standard combo while attacking is a four-hit combo, that can lift him off the ground as he barrages them with a fast and furious flurry of Keyblade slashes and clawing attacks from the free hand, and the combo finisher ends with Terra materializing a large hand of dark energy to deal substantial damage to enemies. The finisher composes of Terra sinking into the ground, homing onto a single enemy and quickly moving under that enemy, and then jumps out of the ground, materializing the hand again straight up into the air, dealing massive damage.

Appearance
When using Dark Impulse, Terra gains a dark aura around him and a black light is focused on his left hand. Wisps of darkness emit from his body as well.

Obtaining Dark Impulse

 * Terra obtains Dark Impulse after visiting the Keyblade Graveyard a second time.
