Light
Light describes illumination, radiant transfer, visibility, and biological responses to strong or patterned light.
Favorable in sanctioned battle Ethereal about +15% damage → A damaging Light technique receives the favorable matchup once when the target carries the listed Current.
Resisted in sanctioned battle Miasma about −15% damage → A damaging Light technique receives the resisted matchup once when the target carries the listed Current.
Native technique about +5% damage If a creature naturally carries Light, its damaging Light techniques receive a separate native-attunement benefit.
If a hit would otherwise deal 100 damage, a favorable matchup makes it roughly 115 and a resisted matchup makes it roughly 85. Attack, Defense, guarding, conditions, critical hits, and battle variance still affect the final number.
