trance

In Final Fantasy IX characters will go into a Trance once their trace gauge is up. Trance only last for a few turns and will "Transform" the character. The character's abilities will improve, and attacks will be more powerful. Here is what happens to characters in Trance.

Zidane: Zidane will become stronger and the DYNE ability will replace the SKILL ability. DYNE will let Zidane use powerful attacks.

Vivi: Vivi will be able to use DBL BLK which will let him use two black magic spells in one turn.

Garnet: Garnet will be able to use EIDOLON which lets garnet summon an eidolon every turn.

Steiner: Steiner's attack power will increase every turn.

Freya: Freya will stay in the air longer when jump is used and every turn will throw spears down on every enemy.

Quina: Quina will be able to COOK which makes EAT more effective.

Eiko: Eiko will be able to use DBL WHT which will enable her to use two magic attacks in one turn.

Amarant: Amarant will be able to use ELAN. I don't know what makes ELAN more special than FLAIR because they do the same thing. It probably does something but I haven't figured it out yet.
