Sound
Sound describes vibration, resonance, frequency, and mechanical waves moving through air, water, structures, and living tissue.
Favorable in sanctioned battle Air about +15% damage → A damaging Sound technique receives the favorable matchup once when the target carries the listed Current.
Resisted in sanctioned battle Miasma about −15% damage → A damaging Sound technique receives the resisted matchup once when the target carries the listed Current.
Native technique about +5% damage If a creature naturally carries Sound, its damaging Sound 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.
