Spontaneous Combustion

is a physical defect that causes the player to randomly erupt into flames.

When a player with Spontaneous Combustion is close to hostile creatures, there is a 0.2% chance every turn for their temperature to raise 400-700 degrees, causing them to instantly catch on fire.

Advantages

 * Grants three extra points to use on character creation
 * The chance to combust is very low and can only occur during combat
 * Can defrost the player if they are frozen in combat
 * With high enough heat resistance it is possible to mostly mitigate the effects of the temperature increase, preventing any actual combustion

Disadvantages

 * No way to know when the combustion will occur
 * Combusting at an inopportune time can make a bad situation even worse
 * Combusting at low health could potentially kill the player
