Dissidia Final Fantasy NT

Compared to its predecessors, the game's battle system is remade from the ground up. The player is part of a team of three charcters, commanding one while the other two characters are AI controlled. A player can choose more than one of the same character on their team, and one-on-one combat is still available.

Playable characters are divided into four combat categories to identify that character's personal fighting style: the power-orientated Vanguards focus on dealing the highest damage and are the designated tanks of the team; agility-based Assassins have fast mobility or very high attack speed; the ranged Marksmen primarily attack from a distance; and the varied Specialists have unique battle traits. All fighting styles, bar the Specialists, adhere to a Rock–paper–scissors rule, with Assassins being strong against Marksmen, Marksmen being strong against Vanguards, and Vanguards being strong against Assassins.

The game retains some core elements from the previous Dissidia games. Characters can perform two kinds of attacks: Brave Attacks and HP Attacks. Brave Attack will decrease the opponent's Bravery stat and increase the attacking player's Bravery by the damage done. HP Attack will inflict damage equal to the player's current Bravery. Decreasing an opponent's Bravery to zero will result in a Bravery Break, giving the attacking player a substantial increase to their Bravery. Characters have seven Bravery attacks at a time: three ground attacks, three midair attacks, and one attack that can be performed while dashing. Each character can equip one HP attack. Some attacks that were HP Attacks in previous titles are now Bravery Attacks. Players cannot customize Brave Attacks and can customize only one HP Attack and two EX Skills. It is possible to save "battle sets" for characters: 1 HP Attack, 2 EX Skills and a costume.

Each character has an independent HP bar, and the party has one HP bar and a summon bar. When the player character is KO'd, one part of the team HP bar is erased. If the global HP bar depletes, the team loses. Double jumping returns, though some characters can now perform triple jumps, such as Lightning and Onion Knight. Dashing now uses up a stamina gauge, and can only be performed for a limited period of time, though the direction can now be changed by using the analog stick mid-air. Dodging is now a step, which has more invincibility frames than the original dodge.

The shield deteriorates slowly and blocks everything, but every time one blocks an attack, the shield starts to break. Shield deterioration is shown as color changes from green to orange to red. When someone is targeting a player, a blue link will appear above them and the enemy's head, and also on the minimap. When the opponent attacks, the blue link turns red to show when to dodge.

EX Mode returns, renamed "EX Skill," and encompasses up to three skills that a character can activate in battle. Some of these skills are based on the original Dissidia EX Modes, such as Terra entering Trance and Cloud entering a "Limit Break" state, while others have support effects, such as Regenga, which recovers the user's HP. EX Skills boost rely on the utility spells encountered in Final Fantasy games. For example, the ability to shield oneself or one's allies, the ability to heal or to use a break attack to destroy the enemy's defense. EX Skills and EX Bursts are available after some time and after using them, one must wait before they become available again. EX Bursts have been made weaker in comparison to the previous Dissidia games where they were often so powerful as to gain an instant win. EX Bursts are also weaker than summons.

Summoned monsters can be called by filling a Summon Gauge during battle by hitting the opponent or shattering crystal cores that appear sporadically, then charging the gauge it to call a summon. If all three members charge the gauge simultaneously, the summon sequence will instantly commence. Summons are auto-controlled allies that assist the player in battle directly, and change the battlefield's appearance (e.g. when summoning Ifrit the arena is engulfed in an aura of fire). The effect disappears as the summon is dismissed after 30 seconds. If the player is hit while channeling a summon, the summoning will be interrupted.

Character customization enables players to swap out colors for each character attire, and also the weapons wielded by them.
