Guide to Traumas
Brain Traumas are afflictions caused by unchecked brain damage. They can severely debilitate players, or very rarely imbue them with supernatural powers, if they're lucky.
A player gaining a trauma will generally see a warning message unique to the trauma.
Trauma Types
You can only naturally gain one Mild Trauma and one Severe/Special Trauma at the same time from brain damage. However other sources of traumas ignore this restriction.
Mild
Mild traumas are relatively easy to get: they require a minimum of 40 brain damage. They can cause minor annoyance in several ways, like stuttering, hallucinations, phobias, or poor balance.
They can be cured fairly easily with Mannitol.
Severe
Severe Traumas require at least 120 brain damage before appearing, making them hard to get randomly. They are severely debilitating, and can range from mutism to complete paralysis.
They can only be cured with brain surgery.
Special
Severe Traumas have a 20% chance of being a Special Trauma instead. Special Traumas grant the player special abilities, although generally with little to no control over them.
Unlike Severe Traumas, Special Traumas are very easily healed, and Mannitol will remove them. Since the player will usually also have a Minor Trauma, this means that it's usually only possible to have both or none.
