Silken Moon's Serenade

4-Piece Set: When dealing Elemental DMG, gain the Gleaming Moon: Devotion effect for 8s: Increases all party members' Elemental Mastery by 60/120 when the party's Moonsign is Nascent Gleam/Ascendant Gleam. The equipping character can trigger this effect while off-field. All party members' Lunar Reaction DMG is increased by 10% for each different Gleaming Moon effect that party members have.

Illuga's Stat Priority
: Elemental Mastery
: Elemental Mastery > Energy Recharge
: Elemental Mastery > CRIT Rate (with Favonius)Illuga should be build almost entirely with Elemental Mastery. Illuga needs enough Energy Recharge to burst every rotation. Generally speaking, you do not want this to be your Goblet build if possible, instead using Favonius for the ER or through good substat rolls if using an EM weapon. When using an EM weapon, because you do not need CRIT Rate, ER becomes your main substat focus.
