Burst Mode (stylized as BURST and abbreviated BT) is a gameplay feature of Dissidia Final Fantasy Opera Omnia. Available to select major characters including one protagonist and one antagonist per game represented, Burst Mode allows the player to execute a series of attacks and complete the combo with a powerful finishing move that can exceed typical 5-digit caps on both BRV and HP.
Mechanics[]
Standard Burst Mode[]
Burst Mode requires the player to obtain a rare BT relic from the in-game gacha, with the probability of such a relic appearing as the +1 in a multi-draw stated as 3%. The first BT relic obtained by the player will trigger a short tutorial. Once obtained, the BT relic must be equipped on the character or mastered to make Burst Mode usable. Each BT relic has a level cap of 50 and a fixed CP capacity of 130, superseding all other relics equipped by the character. BT relics are selectively eligible for realization and limit-breaking in the Global version according to a predetermined schedule, and can be sold for or obtained with Burst Power Tokens through the Token Exchange.
When a character enters Burst Mode, the player will be given six consecutive turns without adding to the normal turn count to select from a dedicated pool of abilities equal to one (1) of each Command Ability learned by the character and create a combination attack, finishing with the designated final attack (Finishing Burst) that can exceed the 99999 limit. The total sum of all damage is displayed after the Burst Mode is complete. The character executing the Burst Mode also gains a temporary Burst Effect for several turns after finishing.
Burst Modes are usable only once per battle, and preclude any summons or friend support the party has equipped; conversely, Burst Modes cannot be activated during summoning because the two features are mechanically similar. When invoked on solo mode support characters, only the Finishing Burst will be executed in a given turn.
Burst+ Mode[]
Once a BT weapon has been realized, it may gain additional abilities aimed at raising built-in damage caps. Although potential damage incurred by the ability may decrease as a result of reduced HP and BRV hit counts, the Burst Mode period adds a seventh turn for the player's use and the Burst Effect gains additional turns. Players may also use the Finishing Burst as a separate ability once per battle. However, if the Burst Effect is already in play, activating the Finishing Burst by itself will not reset the Burst Effect's turn count and will still decrement the counter by one turn. The restrictions on solo mode support remain in effect; therefore, the player will not be able to use a second instance of a Finishing Burst called from a friend support. In co-op battles, each participant can use both instances once each.

Notes[]
- The Onion Knight's Finishing Burst depends on his active job buff; if Ninja, Ninjutsu will be selected; and if Sage, Spellbook will be selected.
- Several characters appear to deal more damage to larger waves of enemies.
