Hemophobe
Melee and ranged attacks within a certain range will cause the attacker to gain the "Bloody" status as long as they deal bleeding damage.
Pawns with the Bloodlust or Psychopath traits will receive a mood boost.
Pawns with the Hemophobe trait or the Hemophobe gene will receive a mood debuff.
The Hemophobe gene can also cause a mental breakdown: Hemophobic Stress. This occurs when a pawn with the "Blooded" status or a bloodstain is nearby.
There is a 50% chance of the pawn running around randomly and a 50% chance of vomiting on the spot.
The mod’s settings will allow adjusting the probabilities for generating traits and genes, with the setting name "Bloody Hell".
Additionally, the mod will allow the setting of whether vampires can have the Hemophobe gene (heh, I just want to see a vampire terrified of blood).
Blood For The Blood God.
