Rhythmia

Rhythmia (abbreviated as rm) is a concept in Theatrhythm Final Fantasy. It is obtained by clearing music scores, and accumulating it leads to various rewards for the player after every 500 Rhythmia gained. At 10,000 Rhythmia, the player immediately encounters Chaos, after which the credits roll and the story is considered completed.

Rhythmia rewards are either new songs to play in Challenge Mode – every 5,000rm from 10,000 up to 25,000 unlocks a new Encore track, and every 2,500rm from 27,500 up to 45,000 unlocks a new Chaos track – shards for unlocking characters, the addition of movies and music to the Museum, or the addition of characters and byline phrases for the ProfiCard. If the player earns a Shard but already has the corresponding character unlocked, they will receive a consumable item instead.

Rhythmia Bonuses
When the player completes any music stage, they always earn a Clear Bonus, Chain Bonus, and Rank Bonus, depending on their clearing the stage, their highest Chain, and the rank grade they receive for their score. The player will also receive a Tactical Bonus, which is calculated based on the party's remaining HP, the percentage of Triggers the player hit a Critical on, what items the player used, and what abilities they activated.

The player can also receive the following optional bonuses by meeting various requirements:
 * Title Character Bonus – awarded when the party includes a character from the same original game as the song. This bonus stacks if the party has more than one such character.
 * All Male/Female Bonus – awarded when all four party members are male or female.
 * Daily/Weekly Player Bonus – awarded based on the consecutive number of days the player has played.
 * Critical Charter Bonus – awarded when the Critical Chart is completely filled.
 * First Clearing Bonus – awarded the first time the player clears a song.
 * Multi Play Bonus – awarded based on the number of people participating in Multi Play in the Chaos Shrine.

Strategy
An effective way to make a large amount of Rhythmia quickly is to make a party of Cecil, Rydia, Kain, and one other character, and use the following Reaction abilities (the player may use any Proactive abilities they wish):
 * Cecil: Fire, Thunder, Blizzard
 * Kain: Focus Lv1, Focus Lv2
 * Rydia: Thunder, Blizzard

The fourth party member can be any character that can equipped with Fire, Thunder and Blizzard at the same time. Vivi, Onion Knight, and Ashe all work for this purpose.

The player should enter Challenge mode and play any Final Fantasy IV BMS over and over. The Tactical bonus will grant the player 50 Rhythmia or more depending on their performance, the large amount of Reactive abilities equipped boosting the bonus greatly (the level one versions of Fire, Blizzard and Thunder need fewer triggers to activate, allowing the player to trigger them more often). In tandem with a +90 Rhythmia bonus for having all three Final Fantasy IV characters in the party, the player can easily earn over 200 Rhythmia per attempt, perhaps going as high as 300.
