This spell summons one of the huge boulders from the realm of the rockfall on the layer of Malbolge in Baator. The boulder is roughly spherical in shape and has a diameter of the caster's level times ten feet. If the caster wishes, it can be made smaller. Any creature beneath the rock can save versus death; success means the victim lived (taking a measely d10 damage per caster level), failure equals death, provided the boulder is larger than victim.
