Siccatite Ingot

ITEM 0
Price 5000 gp
Usage held in 1 hand
Bulk 1

In its raw state, this silvery ore is either scalding hot or freezing cold. Metallurgists disagree over whether siccatite is two related substances or one substance that determines its temperature output via some unknown process. Whatever the reason, the extreme temperature of the material means it must be handled carefully. Hot siccatite can easily ignite flammables such as paper and dry brush, and cold siccatite left in moist areas quickly surrounds itself with a thick layer of ice.

A creature that comes into physical contact with a significant amount of siccatite takes 1 energy damage for each round of continued contact (either fire or cold damage, for hot and cold siccatite respectively).
