Master Vampires can obtain three tiers of emotional dampening perks (Dampened Emotions, Suppressed Emotions, and Deadened Emotions), which progressively lessen the impact of Buffs' mood values on the Vampire. The higher the tier, the lighter the effect those Buffs have on their overall mood.
However, obtaining the perks means having that tier's emotional dampening Buff applied to your Sim — permanently.
What this mod does is tie the emotional dampening Buffs to an interaction to enable or disable them. Once your Vampire has unlocked the perk, they can turn it on and off by clicking on themselves and choosing to Enable or Disable Emotional Dampening, under the Vampire pie menu.
Compatibility
This mod requires the Vampires Game Pack.

NOTE
If your Sim is reloaded or in the middle of another interaction when the toggle is clicked, the animation may not play and/or the toggle may be interrupted. If this happens, just click the toggle again to make sure the Buffs are on your desired state.
