SFP: 25/level
This spell creates a channel of lava by pulling seismic energy from deep underground. The surface solidifies and forms a tube that insulates the lava below so it can travel without losing much heat. The caster can determine where the tube starts and the direction in which it travels. One cubic foot of lava per round for a number of rounds equal to the caster’s level flows out of the tube. (See The Nature of Lava sidebar for game effects.) If the lava flow is blocked, the tube could burst, causing hot lava to splatter within 100 yards of the tube. Earthstokers use this spell to divert flows of lava from an erupting volcano, either as an offensive weapon or else to protect dangerous or sacred territory by ring it with solidified lava.
The material components are a glass tube and a piece of quartz, both of which are burned in a hot fire and consumed.
