Chain Slash (連続斬, Renzokuzan?, lit. Continuous Cut), also known as Chainstrike, Triple Cut, and Slash Flurry, is a recurring ability in the Final Fantasy series. It is an ability used exclusively by Zack Fair.
Chain Slash is the default Digital Mind Wave for Zack, used when no images match up in the slots. Zack does multiple slashes to one target, which deals one hit of non-elemental physical damage to one target, with a power of 48 at Level 1, 54 at Level 2, 60 at Level 3, 66 at Level 4, and 76 at Level 5.
Chain Slash is Zack's first skill and is unlocked by unlocking Zack.
Chain slash is a 5 hit Brv attack that deals more damage if Zack is being targeted by the enemy he is attacking. It also inflicts the Lock debuff which causes enemies to target Zack.
Chain slash is upgraded by equipping Zack with the Hardedge weapon or by equipping Zack with the Pride Carried On passive skill. It increases overall Brv damage and makes Lock last longer
Chain Slash is upgraded again by getting Zack to Crystal level 55 and equipping the Chain Slash Extension passive skill. This adds an HP attack after the 5 Brv hits it also adds 120% overflow to the skill (allowing him to go over his max Brv by 20%). After the skill is used it gives Zack Brv based off of 10% of the HP damage dealt. It also causes his Brv attack to turn into Brv Attack+ after use.
Slash Flurry is an active physical ability that inflicts neutral physical damage on a single target for 6 AP. It has low topple strength. It can be used by Lann (Zack's Champion Jewel).
