Impulse

Impulse (インパルス) is a technique that appears in Kingdom Hearts Re:Chain of Memories. It allows Riku to knock foes into the air before slamming them down to the ground, damaging multiple enemies.

Mechanics
In Kingdom Hearts Re:Chain Of Memories, Impulse is a Duel Sleight that can be used by Riku. He shoots a bright energy ball towards the enemy, in a similar way as when he uses Dark Firaga, knocking it to the air, then rushing forward and jumping up to it doing a downward slash with the Soul Eater until he hits the ground, slamming the enemy and unleashing a shockwave that damages all nearby enemies upon impact.
