Feature Drive

Feature Drive is a gameplay element in Theatrhythm Final Fantasy. If the player has any items or abilities equipped on their party, the Feature Drive is enabled; otherwise, it is disabled ("Stoic Mode").

During the progression of a score, a series of triggers in the Stoic version of the score is replaced by silver triggers; this section is the "Feature Zone". Adequate performance on the Feature Zone diverts the player into the Feature Drive; otherwise, the player continues on the remainder of the score's normal triggers for the span of the Feature Drive. Both the Feature Zone and Feature Drive are marked on the progress bar at the bottom of the screen, indicated by coloured portions of the bar.

The Feature Drive itself has gold triggers, and its nature differs depending on the type of score being played:
 * For Battle Music Sequences, the Feature Drive is a summon sequence, concluding with the summoned monster attacking the enemy. There are five summons: Ramuh, Shiva, Ifrit, Odin and Bahamut.
 * For Field Music Sequences, the Feature Drive is "Chocobo Dash", replacing the walking party member with a chocobo of one of four colours: red, yellow, black or white.
 * For Event Music Sequences, the Feature Drive is "Extended Version", which increases the length of the score with an additional set of triggers. EMS Feature Drives are different to BMS and FMS in that they offer unique content – the full movie playing in the background is only seen in the Extended version.

With the Feature Drive active, the maximum number of points possible for a score is 7,999,999 (which ranks S) if the player achieves All Critical. SSS rank (9,999,999 points) is only achievable by removing all abilities and items from the party, and thus receiving the two million point Stoic Bonus in addition to a 7,999,999 point All Critical.

In order to fill the Critical Chart for a score, all triggers in both the Stoic branch and the Feature Drive branch must be hit critically at least once, meaning that no Critical Chart can be completed in fewer than two plays through the score.
