Moonlight, Lent Unto You
When a party member triggers an Electro-Charged, Bloom, or Hydro-Crystallize reaction, it will be converted into a Lunar-Charged, Lunar-Bloom, or Lunar-Crystallize reaction respectively. Lunar Reaction DMG inflicted by party members gain a Base DMG increase based on Columbina's Max HP. For every 1,000 points of Max HP, the Base DMG of Lunar reactions is increased by 0.2%, up to a maximum of 7%.
Additionally, when Columbina is in the party, the party's Moonsign will increase by 1 level.
