Slit Edge

Slit Edge is one of Shulk's arts in Xenoblade Chronicles. When used from the side it inflicts a Phys Def Down debuff, reducing the enemy's Physical Defence by 50%. In Xenoblade Chronicles X it is an art exclusive to the Drifter class and as such it can only be learned by Cross. In this game, it will deal a 50% extra damage if it hit the enemy on the side. The secondary cooldown gives a 250% damage up and the Tertiary cooldown gives a 400% damage up.
