Boil Water

Regular 
Turns water into steam. Water expands considerably in going from liquid to gas; a mere pint of water makes a lot of steam. The scalding effect of steam is such that a steam hex should be treated exactly as a fire hex, except that it cannot ignite anything.

Duration: Permanent, though the steam will re-condense naturally (within about 10 minutes). 
Cost: 2 for a fist-sized quantity of water (makes about a hex of steam), 4 for a cubic foot’s worth (makes about 40 cubic yards of steam), 6 for a square yard of water to a foot’s depth (makes about 400 cubic yards of steam), 3 for each additional third of a cubic yard. 
Time to cast: 10 seconds. 
Prerequisites: Shape Water and Hazards and Afflictions/Heat.

Item 
Staff, wand, or jewelry.  
Cost to create: 200 energy and a $100 carnelian.
