Byblos's Vengeance acts similar to the Lifebreak spell, dealing damage equal to the difference in the user's Max HP and current HP. Byblos already knows this ability when he joins the party.
Templars can use Lifebreak learned for 300 AP from the Kain's Lance, and deals damage equal to the HP lost. Curiously enough, the ability is Dark elemental, and thus the damage will be reversed on undead enemies. The range of the ability is equal to the weapon currently equipped.
Snipers can use Doom Archer. However, Doom Archer's damage is split between HP and MP.
- Templars can use Lifebreak that is now Dark-elemental.
- Master Monks can use Withering Strike, a ranged version.
- Tricksters Agitate and Heritor's Viola are area-of-effect versions of Lifebreak.
- Snipers can use Marksman's Spite. Marksman's Spite damage is split between HP and MP.
- Salve-Makers can create the Dark Breath effect using Compounding.
