Pillar of Borogar

This spell, first bestowed to the ancient dwarven high priest Borogar, causes a pillar of earth to erupt upward from the ground. The pillar rises from a surface of earth, stone, sand, or clay, but not from any other substance. The height of the pillar is controlled by the caster, and can be raised or lowered at will (in the same manner as an elevator is controlled). The pillar can be controlled while the caster is atop the pillar or beside it, as long as the caster is within 30 feet of the pillar. The pillar can attain a height of 10 feet per level of the caster, and can rise or fall at the rate of 60 feet per round. The pillar's width is normally 10 feet in diameter, but this can be doubled to 20 feet by reducing the height by half. Altering the pillar's diameter in this way takes one round.

The pillar rises only vertically – not horizontally or diagonally. The pillar can break through flooring wood or roofing slate of no greater than 1 -inch thickness. Thus, the pillar can be used as a vertical battering ram against light, thin materials.

The pillar of Borogar can be used to create a small, temporary islet in a marsh or shallow pool of water, if the pillar can be raised from the ground below the water to reach the surface. The pillar begins, not from the upper level of the submerged ground, but from 10 feet lower, where the earth is more solid and not muddy.

The pillar can be destroyed by casting a transmute rock to mud spell at its earthen base, by a water elemental's attack, by precipitation equal in strength to a tropical storm, or by any other means that turns the pillar's earthen base to muck and mire.

The material component is a small cylinder made of earth or clay.
