Ruinga

Ruinga is a recurring ability in the series, originating from Final Fantasy XIII. It is a non-elemental magic attack that hits all targets in an area and is associated with the Commando job.

Final Fantasy XIII
Ruinga is an offensive spell in Final Fantasy XIII that deals non-elemental magic damage to all enemies in an area and has a chance of launching them in the air. It can be used by the Commando and requires three ATB charges to cast. It is the Tier 2 equivalent of Ruin.

All characters are able to learn Ruinga:
 * Lightning at Stage 8.
 * Sazh at Stage 9.
 * Snow at Stage 8.
 * Vanille at Stage 10.
 * Hope at Stage 9.
 * Fang at Stage 8.

Ruinga is especially useful against a group of fast enemies, such as the enemies at Sulyya Springs, because it interrupts the enemies' actions when used and stops them from ganging up on a single character.

Final Fantasy XIII-2
Ruin and Ruinga returns in the sequel of Final Fantasy XIII. Not much has changed since and the respective spells retain their respective ATB cost and effect. However, using En- spells to adjust the element has become a less favorable option due to the En- spells being taught to only a few monster Synergists, and often the monster Synergist learn only one En- spell.

Both Serah Farron and Noel Kreiss learn Ruinga at level 33. Lightning can also use Ruinga at the player's discretion during a Cinematic Action sequence in the game's opening.
