Magma Tunnel

''By heating the very fabrics of earth, you create a flow of magma, which burrows a tunnel. The magma is accompanied by a sulphurous smell and misty vapors. When the magma hardens, you can pass through unharmed.''

You can tunnel through solid earth, rock, sand, or silt, by liquefying it into flowing magma. The liquid rock moves out of the way to allow you to pass, and hardens in that position, creating a permanent, nonmagical tunnel. The tunnel forms at a rate of 30 ft./round through sand, silt, or wood, 20 ft./round through solid earth and 10 ft./round through rock or metal. Any creatures or objects caught in the magma current while the tunnel is being created suffer 10d6 points of fire damage (Reflex save for half damage).

It takes one day for the heat to dissipate enough for the unprotected to enter, although you are magically protected for the duration of the spell. Creatures entering the tunnel unprotected during this time suffer 1d6 points of fire damage per round from the extreme heat. The tunnel is formed at a rate of 30 ft/round through sand, silt or wood, 20 ft/round through solid earth and 10 ft/round through rock or metal. Any creatures or objects caught in the magma current while the tunnel is being created suffer 10d6 points of fire damage per round
