Buster Sword Gameplay Changes

The Buster Sword adds a new Battle Stance called for Zack Fair. It is akin to Cloud Strife’s Punisher Mode from Final Fantasy VII Remake. To enter this stance, the player has to press the Attack and Dodge buttons at the same time. Activating the stance takes some of your AP.

While this stance slows the player down, it allows for devastating damage and also gives a passive guard ability. You will also regain some MP and AP every time you kill an enemy during Battle Stance.

Proficiency Stat

Buster Sword is accompanied by its own status called Proficiency. Proficiency, as the name implies, affects how well you can use your weapon. This status can be increased by ‘

  • Guarding against enemies’ attacks during Battle Stance.
  • Killing enemies in the Battle Stance.
  • Using a Command Materia to kill an enemy while in Battle Stance. 

These actions gradually increase your Proficiency status. Interestingly, Proficiency will cap at 95 percent instead of 100. This is a nod to the legendary Cloud Strife, overcoming his shortcomings and became the true master of the Buster Sword.

Abilities Unlocked By Proficiency

Increasing your Buster Sword Proficiency in Crisis Core Reunion FFVII unlocks new abilities for your weapon. These abilities are

  • At 23 percent Proficiency: You will be able to break the 9999 damage limit by using attacks and command materia in Battle Stance. 
  • At 47 percent Proficiency: While in Battle Stance, any attacks or command materia you execute will pierce the enemy’s Barrier.

No further abilities are unlockable after reaching 47 percent proficiency. As such, players should only grind until 47 percent, as there is no incentive to grind more after that.
