Encase
(Evocation)(Elemental (Earth))

Range:  10 yards per level
Components:  V, S, M
Duration:  1 turn + 2 rounds per level
Casting Time:  4
Area of Effect:  One creature of size Large or smaller
Saving Throw:  Negates

When cast, this spell completely encases the target in volcanic rock. The casing does not hinder breathing due to its porous nature, and the victim suffers no damage; however, it does block vision and prevent all movement for the duration of the spell, including somatic and verbal spell components.
If the target saves versus spell, he completely avoids the effects of encase, as a hollow stone statue roughly his shape appears next to him, collapses in on itself, and disappears. If the target fails his saving throw, he is immediately encased. Each round thereafter, he may attempt to break free. Breaking free requires the entire round and a successful bend bars/lift gates roll.
The volcanic casing will crumble after suffering 15 points of damage plus 1 point per level of the caster. For damage purposes, treat the casing as having an Armour Class of 5. Any attack that damages the casing has a 3/4 probability of wounding the victim within; divide the damage equally between the casing and the victim. In addition, the victim automatically incurs all damage above the amount required to destroy the casing. For example, Chluckla is encased by a 10th-level priest, creating a casing with 25 HP. His comrades attempt to free him by chipping him free. Blitz strikes the casing and does 6 points of damage and rolls a 2 on 1d4 - the casing takes 3 points of damage and Chluckla takes 3 points of damage. Taraq does 12 points of damage and rolls a 4 - the casing takes all 12 points of damage. Finally, Morgart does 28 points of damage, rolling a 1 - Chluckla takes 14 points of damage, and the casing takes 14 points; however, since the casing had only 10 HP left (25-3-12), the remaining 4 points damage are applied to Chluckla. Thus, Chluckla's friends inflict a total of 21 points of damage (3+14+4) to him while trying to free him.
A successful dispel magic will immediately remove the casing. The material component for this spell is a fist-size piece of volcanic rock.
