Artwork was produced by manga and anime artist Nobuteru Yūki, while the music was composed by Secret of Mana composer Hiroki Kikuta.

The game was designed by series creator Koichi Ishii, directed by veteran Square designer Hiromichi Tanaka, and produced by Tetsuhisa Tsuruzono. Trials of Mana builds on the gameplay of its predecessor with multiple enhancements, including the use of a time progression system with transitions from day to night and weekday to weekday in game time, and a wide range of character classes to choose from, which provides each character with an exclusive set of skills and status progression. It features three main plotlines and six different possible main characters, each with their own storylines, and allows two players to play simultaneously. Set in a high fantasy world, the game follows three heroes as they attempt to claim the legendary Mana Sword and prevent the Benevodons from being unleashed and destroying the world.

It is the sequel to the 1993 game Secret of Mana, and is the third installment in the Mana series. Trials of Mana, also known by its Japanese title Seiken Densetsu 3, is a 1995 action role-playing game developed and published by Square (now Square Enix) for the Super Famicom.
