Characteristics
When they woge, Excandesco take the form of a human comprised of jet black ingenious rock. They have three digits on their hands and feet. By releasing large amounts of white phosphorous though their skin, Excandesco can generate intense flames. This power can be accessed regardless of if they are woged or not.

Slathering their bodies while they are woged with a sticky fire retardant (such as a combination of crushed up licorice root with beeswax, witch hazel, and jojoba) will prevent them from conjuring fire. Consequently, the energy will be turned inwards, causing them to explode. They usually take off the majority of their clothes before they woge to avoid burning them.
