When at low health, Enki may boost its stats with Bellow, then enter an Enraged status and release its Raging Torrent attack, which deals heavy Water damage. Raging Torrent also damages Enlil if it is nearby.
Enki has marginally more HP than Enlil, so Enlil should be taken care of first. Once Enki is alone, Vanille and Sazh can cast Thunder to exploit its weakness. Sazh can also cast Enthunder on himself and Vanille to add an extra spark to Commando and Saboteur abilities.
Another good strategy is to draw Enki and Enlil near each other and try to get both enraged; their attacks Raging Tempest and Raging Torrent will affect each other, and since they are opposing elements, these attacks do massive damage.
