I came here expecting vitriol, was pleasantly surprised.

To the OP: All raids/ex primals have an enrage which comes in the form of either a single attack which instantly wipes the party (hard enrage) or a series of attacks which become increasingly difficult to deal with, at which point you wipe from lack of MP (soft enrage). Enrages come after the boss finishes their battle script or a certain amount of time has passed (usually between 8-14mins), if you do not kill the boss before this then you are not meeting the DPS requirements.
