Ice
Ice describes heat loss, freezing, phase stability, and structural effects of water held below its ordinary liquid range.
Favorable in sanctioned battle Water about +15% damage → A damaging Ice technique receives the favorable matchup once when the target carries the listed Current.
Resisted in sanctioned battle Fire about −15% damage → A damaging Ice technique receives the resisted matchup once when the target carries the listed Current.
Native technique about +5% damage If a creature naturally carries Ice, its damaging Ice 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.
