Forbidden Secret Manual (II) is needed to unlock this skill, available through the Power of Transcendence Skill Quest or Item Mall.

This skill deals splash damage, allowing for very high damage on tightly packed enemies.
- Also because of this, the skill returns an incredible amount of MP when fired at multiple enemies, gaining well over its own cost back on any more than 4 enemies.
- The explosion that occurs at the maximum range of the skill can also hit an already pierced target, so taking proper distance is advised when attacking a single target.
  - The maximum range of this skill extends roughly to the edge of your screen.
