As of 04/21/2016 in KR, this skill pierces, while keeping its ability to deal splash damage, allowing for very high damage on tightly packed enemies.
- Also because of this, the skill now 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.
