Sacrifice

Sacrifice (ソウルリリース) is a technique exclusive to Terra in Kingdom Hearts Birth by Sleep and is exclusive to Riku in Kingdom Hearts 3D: Dream Drop Distance. It allows the user to execute a powerful attack at the expense of HP. Although Sacrifice is meant to be used in combat, it is also effective at quickly reducing the character's HP to below 25%, activating EXP Chance and Reload Boost. In addition, if Limit Storm is used immediately after Sacrifice, it will execute much faster than it normally does.

The attack is similar to the Souleater command in the Final Fantasy series, which usually allows the user to expend some of their HP to execute a strong attack.
