There are several sections of the game where Clive will become fully primed and embody Ifrit the Eikon. During those sections of the game, he will have access to some or all of the abilities noted below. Without delving too much into the story (and in an attempt to prevent spoilers), there is more than one fight as Ifrit, and you will gain access to additional abilities for the fights that occur later on in the game. To reiterate, this means that you may not see all of the abilities listed below every time you embody Ifrit.
