Shadowless Reflection
Q. Elemental Burst

Shadowless Reflection

Light the lamp, dealing AoE Geo DMG, and gain Haunted Night's Oriole-Song effect for 20s. When this effect is active, Illuga gains 21 stacks of Nightingale's Song. When Normal Attacks, Charged Attacks, Plunging Attacks, Elemental Skills, and Elemental Bursts of nearby active party members deal Geo DMG to opponents, 1 stack of Nightingale's Song is consumed to increase the DMG dealt. Increase in DMG is based on Illuga's Elemental Mastery. If DMG is inflicted by Lunar-Crystallize, DMG dealt will increase further.
When Geo DMG dealt in this manner hits multiple opponents, multiple stacks of Nightingale's Song will be consumed, depending on how many opponents are hit.

Additionally, if there are Geo Constructs created by nearby party members on the battlefield while Illuga unleashes his Elemental Burst, or when nearby party members create Geo Constructs while Haunted Night's Oriole-Song is active, every Geo Construct on the battlefield will allow Illuga to gain 5 additional stacks of Nightingale's Song. Within 20s after unleashing his Elemental Burst, Illuga can gain a maximum of 15 additional stacks of Nightingale's Song this way.

When all stacks of Nightingale's Song have been consumed, or when the state's duration ends, the Haunted Night's Oriole-Song effect will end.
● Nightingale's Song
The effect gained after Illuga unleashes his Elemental Burst Shadowless Reflection. It can increase the Geo DMG inflicted by current active characters.

Default

Illuga's outfit is a custom-made uniform that was designed with his duties in mind. Though it is technically meant for work, Illuga has so many responsibilities that he rarely gets the chance to change his clothes, so in practice, this uniform might as well be considered his everyday wear.

Stories

Spring in Nod-Krai is cruel. Unlike the Northlands, where snow blankets the earth through all four seasons, denying even a glimmer of hope to the life buried beneath, the spring in Nod-Krai ushers in a false sense of optimism. As the bitter winter loosens its grip, the frost melts into the thirsty soil, and seeds buried deep since the year before drink once more of the sweet, damp earth. They sense warmth above and stir, believing the frigid foe who shattered their stems and leaves has vanished with the passing of time — spurred by that fleeting promise, tender sprouts strain to push through the cracked earth and taste the air above. But it is all a lie — a trap woven for the unwary. A single night of early-spring frost is enough to obliterate all their efforts, leaving behind an empty wilderness — desolate, broken, barren. Spring in Nod-Krai is cunning. But if a plant can survive the recurring wind and frost — a harshness that the very earth itself seems weary of — then even the humblest Winter Icelea can find sunlight in a world reborn. It is a reward for resilience, or perhaps for courage, though the two are often intertwined. Perhaps for this reason, the Lightkeepers of Nod-Krai are known to liken themselves to Winter Iceleas. Yet those who endure the bitter cold and survive the early spring are few. And rather than a plant, Illuga — who grew up in the shadow of the lighthouse — dreams of becoming the sunlight itself. In a tale passed down among the Lightkeepers and known to few beyond, nightingales carrying burning wicks in their beaks take flight in darkest night and streak through the sky like shooting stars, the smoldering blades of grass they hold bestowing the light of day. Illuga never told Nikita that he preferred to be a nightingale rather than a Winter Icelea.
