This power can be activated at any point during the initiative order with no action cost. It can also be activated preemptively outside of initiative order to prevent specific effects, as described below. Once activated, the vampire gains a specific immunity based on the Resonance of the blood they most recently fed upon. • Choleric: While active, the first time a stake would usually pierce the vampire's heart, it instead decays to ash without doing any damage. • Melancholy: While active, the first three damage a vampire takes from fire damage is automatically reduced to Normal damage. • Phlegmatic: When active, the first time an Auspex power is used during a scene to reveal something about your character or something they know, the power fails without a test. • Sanguine: During the scene, the first four damage a vampire takes from the sun is automatically reduced to Normal damage. Once any of these four effects are triggered, the Resonance of the blood weakens, and the vampire must feed before activating this power again. If they have a Dyscrasia card, they may keep and use it as per usual.
