Fighting with a will of their own, Eidolons serve as powerful allies. In gestalt mode, players can perform punishing attacks from the back of a transformed Eidolon.
Players can summon the battle team leader’s Eidolon by expending technical points. During normal mode, Eidolons will take the place of the other party members and fight alongside the summoner. SP represents both the Eidolon’s HP and time gauge. When SP reaches 0, the Eidolon will leave the battle.
Also present during normal mode is the gestalt gauge. This gauge fills up as the player chains attacks with the Eidolon.
At any time before SP reaches 0, the player can initiate gestalt mode. In gestalt mode, attacks are dealt through the on-screen button commands, each with an associated time unit cost. The number of time units that can be allocated depends on how full the gestalt gauge was. When all points have been expended, the Eidolon will be dismissed, but not before restoring the entire party’s HP and also removing any status ailments.
