Dracofrenia

Dracofrenia is a common condition among monsters, allowing them to undertake a dragon-like form when they are angry or upset.

How do you get this disease?
This is a non-contagious condition, (aka it's barely even a disease) and you can only get it if someone in your family has had it, or if you get a certain kind of curse.

Currently, the only character with Dracofrenia is 18.

How can you cure this disease?
Currently, this disease is uncurable, but that's ok I guess because it's not that dangerous to the person with the disease. As long as you're not around them when they're angry, then you're okay.
