A Limit Break (リミットブレイク, Rimitto Bureiku?) is a powerful ability introduced in Kingdom Hearts 358/2 Days. During a Limit Break, the user unleashes a tremendous amount of power as an attack that they wouldn't normally be able to perform. The attack is usually based on the user's element or abilities in previous games, such as a combo finisher or Limit. Unlike a Limit from Kingdom Hearts II, the character can take damage if attacked while performing a Limit Break, although the damage taken is less. It also heals the character from any negative status effect, and prevents them from getting any status effects.
In order to activate a Limit Break, the user must drop into a low amount of their HP, also known as the Alarm Zone. This area is marked as being yellow, as opposed to the rest of the green bar. After having dropped into the Alarm Zone, a small sound will play; at this point, the Limit Break can be unleashed by holding . Once the powerful attack has been triggered, a white marker will begin to move down the HP bar, until it reaches the far left end. At that point, the Limit Break ends, and the Alarm Zone is set closer to the right end of the HP bar. To use the Limit Break again, the user must survive another attack to re-enter the Alarm Zone.
The placement of the Alarm Zone can be altered by certain panels:
On Day 225 of the Story Mode, Roxas will receive the Final Limit (リミットカット, Rimitto Katto?, lit. "Limit Cut") panel from Saïx, which allows to user to execute their Final Limit. During Final Limit, the user will gain additional attacks not available in a normal Limit Break. Final Limit will activate when a normal Limit Break would end: when the white marker reaches the far left end of the HP bar. The marker will then move back along the HP bar until it reaches the Alarm Zone, at which point Final Limit will end.
The Limit Pass (リミットオープン, Rimitto Ōpun?, lit. "Limit Open") panel allows for configuring Limit Breaks in Mission Mode, under the "Mission Config" menu. Unlike other Panels, the Limit Pass does not appear in Roxas's inventory, and does not need to be equipped to be active. It can be purchased at the Moogle Shop for 10000 Heart Points, once all Missions in Mission Mode have been cleared. Three settings are available:
