Elemental Mastery

Lightkeeper's Oath doesn't apply to Illuga.
Nightingale's Song starts at 21 stacks; each Geo Construct on field when Burst is used—or created during it—adds 5 stacks, up to +15.
Lunar-Crystallize Moondrifts count as Geo Constructs.

OFF-FIELD BUFF SUPPORT
Elemental Burst applies Nightingale's Song, buffing Geo DMG and Lunar-Crystallize DMG; scaling off Elemental Mastery, with A4 amplifying it per Geo/Hydro ally in the party.
A1: Skill or Burst grants allies Lightkeeper's Oath — CRIT Rate and Geo DMG bonus, plus Elemental Mastery while Ascendant Gleam is active.
C1: triggering a Geo reaction on-field restores 12 Energy (15s CD), effectively lowering Burst cost from 60 to 48.
Weapon: Dragon's Bane — an Energy Recharge sands may be needed without enough ER substats.
Artifact: Silken Moon's Serenade (4) requires C2.
