Other supernatural creatures tend to have aura effects that force Conditions. Sometimes this is a defence mechanism; sometimes this is a way to assert dominance.
However, mages are particularly resistant to this effect. When such an effect targets your character, roll a dice pool comprised of a Resistance Attribute + Gnosis. The Resistance Attribute depends on the monster’s dice pool:
If it uses Strength, roll Stamina; if Presence, roll Composure; and if Intelligence, roll Resolve.
This resistance is automatic, but it does count as flaring your character’s Immediate Nimbus. This comes with all effects, both positive and negative. The roll acts as a Contested Action against whatever the other character throws at yours. Your successes subtract from his; if you net any successes beyond his, he suffers your Nimbus Tilt.
