When cast, Sacrifice creates a glowing red 死 (Shi - Death) kanji character over the target, wreathed in red vapor and emblazoned over a red and black "burst" detail.
Sacrifice kills the user to deal massive Dark-elemental damage to a single enemy, with a small chance of inflicting Instant Death to the target. The act of sacrifice cannot be blocked by Instant Death resistance, Bless or Morale, but will still trigger Auto-Revive. It also has no impact on the Limit Break bar.
Dark Godcat can also use Sacrifice, without any negative consequence to herself.
