Headcanon: Soul Sickness
Refer to Monster Soul, Physicality, and Heartbreak headcanons Soul illnesses and Body illnesses are two separate things. A body illness is something a monster with higher physicality is more prone to, though that doesn’t stop a less physical monster from getting them (it just lowers the chances drastically). Body illnesses include things such as: Cold, flu, diabetes, heart disease, liver failure, and pretty much anything a human can develop. The more physical a monster becomes, the more physical illnesses they become prone to. A soul illness is something brought on by mental and emotional instabilities. As a monster’s soul regulates all magical function, the more strain it takes on, the less physicality there is. The more physicality there is, the less hard a soul has to work to keep the monsters together (Aka: to keep the monsters being from splitting apart and turning to dust). Monsters need a mix of magical and physical build. If their body consists of one more than the other, their soul either becomes too strained (little physicality), or hardly needs to function, which can result it in stopping the flow of magic or becoming too weak to pump magic through the monster should something happen to their physicality. This can result in death. Anyway, back on topic... A Soul Sickness is brought on when an already strained soul is forced to also burden the task of emotional and/or mental instabilities. A monster can become sick during this time and remain ill, without the option of being healed -- because it’s an emotional distress, not a physical one -- until the monster’s soul can properly regulate the magic again. The weaker the monsters, the more dangerous this is. Monsters can die if their emotional state is too much for an already strained soul to handle.
