In addition to Standard Battles, NT features a second battle type in the form of Core Battles. By filling their team's Summon gauge, players can perform summons to call one of seven creatures such as Ifrit or Bahamut to attack their enemies, as well as grant passive buffs to the player's team.

Players can also fill their Summon gauge by attacking foes or destroying Summoning Crystals. Players can use their shield or dodge to defend themselves, though the shield will deteriorate over time. Energy from the Stamina meter is expended when the player performs a dash or dodge to limit overuse the meter will quickly recharge if the player remains on the ground for a short time. When a character is defeated, a segment will be removed from their team's Party HP meter when the meter is depleted, the team loses the battle. Each character has its own HP meter, along with a Party HP meter, Stamina meter, and Summon meter for the whole team.

Unlike past Dissidia titles, NT places a focus on three-on-three combat, with players actively controlling one character while the in-game AI controls the other two. The previous games' EX Mode has been tweaked, with players able to equip one HP attack and two EX Skills per character in battle. Using HP attacks will reset the player's Bravery back to zero, forcing them to perform more Brave attacks before they can directly attack their opponent again. Players can also perform HP attacks that will do direct damage to an opponent based on their current Bravery level. If an opponent is attacked while their Bravery is at zero, a Bravery Break will be triggered, giving the player a substantial Bravery boost. Characters can perform Brave attacks, which increase the player's Bravery level based on the amount of damage done. Characters are divided into four combat classes: power-based Vanguards, agility-based Assassins, range-based Marksmen, and unique trait-based Specialists. Dissidia Final Fantasy NT's battle system was redesigned from the ground up, though some elements from the previous titles have been retained.
