Ethereal
Ethereal is the Collegium label for repeatable effects that couple weakly to ordinary matter yet recur around attention, memory, and places of repeated significance.
Favorable in sanctioned battle Light about +15% damage → A damaging Ethereal technique receives the favorable matchup once when the target carries the listed Current.
Resisted in sanctioned battle Void about −15% damage → A damaging Ethereal technique receives the resisted matchup once when the target carries the listed Current.
Native technique about +5% damage If a creature naturally carries Ethereal, its damaging Ethereal 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.
