- Lucil: "Lady Yuna, if I may?"
- Yuna: "I’d be honored."
- Lucil: "The honor is mine. Please, be gentle."
- —Lucil and Yuna
Lucil's attacks are mostly physical in nature but she can also perform an attack called Harbinger, which causes Doom. The only way to counter that is to either kill her quickly or use Ribbon or the Bitter Farewell Garment Grid and pass through the yellow gate for Doomproof. Lucil uses elemental items.
Using Force of Nature or any elemental absorbing/nullifying accessory, dressphere, or Garment Grid helps as well, against Lucil's elemental items. Combining Ribbon/Doomproof with Force of Nature pretty much ensures victory, as the only way for Lucil to defeat the player is to physically attack, which is not much of a threat.
Lucil is an optional boss in the Fiend Arena in the Youth League Tournament. She is fought either by by herself, or together with Yaibal and Elma.
