This spell opens a small gate to the plane of magma. A large drop of magma enters the prime material and flies toward the target, coating him with burning lava. This causes 2d12 points of damage, plus 1d6 on the next two rounds, unless the target makes a save vs spell, in which case he suffers only 1d12 damage. Material component is quartz gem, which is consumed during the casting. The sheet is 2 cm thick, and the imprisoned creature is protected by attacks from outside the shell, need not air to survive, and have all metabolic and body functions halted, except thinking.
Material component is a piece of gargoyle skin.

Any creature trapped in the area suffers 1d4 points of damage each round. Each point of magical AC reduces damage by 1 point, down to a minimum of 1 point. Material component is a caltrop.
