Description: You conjure a large metal cube covered in sharp spikes. If you conjure the block so that it appears in midair, it immediately plummets downward onto all creatures below it. When you cast this spell, you select the size of the square area you wish it to affect from 5'x5' up to 25'x 25'. At 5'x5' the cube does 8d6 hp of damage. At 10'x10' divide the damage by 2; at 15'x15' divide by 3; and so forth. Only creatures that are on the outer edge of the area affected by a conjure deadfall spell can attempt DEX saves to avoid the effect; creatures whose space does not touch the edge of the deadfall do not receive a save. In order to deal damage, the conjured deadfall must start at least 10 feet above the tallest creature in the area to be affected. A conjured deadfall is as tall as it is wide, and the spell fails if you attempt to conjure a deadfall in an area already occupied by a creature or object (including the ceiling). Regardless, a deadfall conjured by this spell disappears as soon as it deals damage or strikes the ground.
Leveling: For each level above the minimum, add 2d6 hp of damage.
