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.
