Limit is a command ability in Final Fantasy VII Rebirth used to perform special abilities unique to a party member, available once their limit gauge is full. They do not consume ATB charges and either deal significant damage to enemies, or have powerful supportive effects. When used, the camera will focus on the party member while they are performing their ability, unless the player switches to another party member.
Each party member has three limit break levels, and unlike in Final Fantasy VII Remake, every limit break can be used at once by a party member if they have higher limit levels. Every major character starts out with two limit breaks and can unlock a third one via their folios. Level 2 and 3 limit breaks are available either through accessories, by using synergy abilities, or Cait Sith'sLucky Slots three stars outcome, to reach higher levels, and perform more powerful limit breaks.
A party member's limit gauge fills by taking damage in battle. Through materia, accessories, and unlocked folios, it can also increase through other effects, such as staggering enemies or consuming MP. When a limit bar is filled, a limit break can be used at any time outside of an enemy's cinematic attack/scene transition.
The party member is immune to damage while using a limit break. Using it does not stop an enemy action, meaning there is some possibility the enemy may avoid the attack, or that they may be invulnerable to damage.
The limit gauge is only set for the battle in question. When a new battle begins, including a new round in battle arenas, the limit gauge remains. It does not disappear when a party member is KO'd.
