Terra's Trance is enabled when she rejoins the party in Zozo. While Terra is transformed, the damage she deals is doubled and the magic damage she takes is halved. Her ATB gauge is replaced with a green gauge that slowly decreases, and when it empties she turns back into a human. The length of time Terra can stay in Trance depends on the amount of Magic AP she has gained after battle. If she has not gained enough, she cannot enter Trance, and if her Trance gauge depletes during battle she will not be able to enter Trance in the next battle until she acquires enough Magic AP again. The maximum amount she can have is 255. Terra can also change back into a human at will with the Revert command.
