Rock to Magma (Drd/Sor/Wiz 6)

   This spell transforms the top 1 inch of
rock to magma. This transmutation will not destroy the rock
or any rock beneath this 1 inch thickness. The caster must
concentrate and have one hand always touching the rock while
the spell is in effect.

   The spell will begin to heat up the rocks
slowly altering the temperatures on the rock surface to unpleasent
degrees.

   Subjects making a reflex save may use their
movement to get out of the heated rocks only taking 1/2 damage.
If the save fails they take full damage and fall on the heated
rocks. A save must be made every round a subject is in the
affected area. Subjects not in or having light foot wear make
a save at -2. Damage is done at the start of every combat
round.

Damage after spell is completed per round:

1st rd: 1d4 per caster level
2nd rd: 1d6 per caster level
3rd rd: 1d8 per caster level
4th rd: 1d10 per caster level
5th rd or beyond: 1d12 caster per level
