Death blow
Death blow is a special ability of the Dread Knight, which gives them 20% chance of dealing double base damage when attackin a creature stack. The game infromation states that Dread Knights would deal double damage when the death blow occurs, but that is not technically correct as it only doubles the base damage. In other words, bonuses from Offense, Luck or attack-defense difference are not doubled. See damage calclulation for more specific information about the matter.
