Armor-penetrating attack. Also hits unit behind.
Piercing Blow (ハードインパルス, Hādo Inparusu?, lit. Hard Impulse), also known as Piercethrough, is a recurring ability in the series. It is an ability used exclusively by the Fencer class. It allows the user to hit multiple targets with a single strike.
Piercethrough is an ability learned by the Fencer class for 200 AP from the Flamberge. It deals damage up to two targets if they are standing behind one another, up to two spaces in front of the user.
Piercing Blow returns as an ability learned by the Fencer class for 300 AP from the Flamberge. It is otherwise the same as its previous version.
