Brave Exvius is designed as a turn-based role-playing game, using elements from the Final Fantasy series with those of Brave Frontier. Similar to Brave Frontier, the battle system consists of a simplified interface where players can command their characters to attack by touching the character's corresponding attack button, and special attacks or items can be used by swiping the button and choosing the desired command. Players advance through a series of stages until they encounter and defeat the end boss, all while gaining experience points, crafting materials and money.
The game also uses elements from the Final Fantasy series such as magic spells, character-specific limit breaks, and summon monsters. As part of the game's gacha system, players can summon characters from other Final Fantasy titles, which players can use to build a party of five units. Characters are presented in a pixel art style. Also new to the game compared to Brave Frontier is the ability to explore through towns through touch control in a classic RPG style, which allows the player to talk to people and interact with them, which sometimes gives the player certain tasks to complete. Also after completing one dungeon, they can also wander through dungeons which also allows them to obtain more items and complete certain tasks.
