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.

The attack is initiated by shooting a ball of energy at the enemy, similar to Dark Firaga, knocking it into the air. The user then executes a high jump towards the enemy, followed by a powerful downward strike that slams the enemy to the ground and unleashes a shockwave that damages all nearby enemies upon impact.

Mechanics
In Kingdom Hearts Re:Chain of Memories, Impulse is a Duel Sleight that is activated by winning a three-card duel against an enemy.
