Resonance is a new feature introduced in Bloodlines 2. When vampires feed on human victims their blood can imbue additional effects depending on the emotional state of the victim at the time of feeding, giving their blood a kind of 'flavor'. According to the developers, it is intended to emphasize the idea of "you are what you eat" and will give an additional incentive to feed even when the player's Hunger is completely satiated. It will also act as a secondary XP system to unlock and activate Resonance-specific buffs, known as 'Merits'.
The Resonances currently known to be in the game are:
It is not yet known what the specific effects of feeding on each Resonance will be, or whether Dyscrasia (clots, a build-up of resonance) from the V5 VTM tabletop game will be incorporated. The Protagonist will be able to view the emotional state (and therefore Resonance) of potential victims using their enhanced vision.
