Wall of stone

Wall of stone was a conjuration or evocation spell that created a mutable stone wall.

Effect
As the name suggested, wall of stone created a wall made of stone. The thickness of this wall increased with the caster's skill. The same applied to the area the wall occupied. This area could even be doubled by halving the thickness.

While the spell was called wall of stone, the result did not need to be a wall. At the caster's discretion, the wall of stone could be turned into practically any shape, as long as the wall of stone was rooted in existing stone. For example, the wall of stone could be made to create a magical bridge. If the length of this bridge did not exceed 20 feet (6 meters), this bridge did not need to be arched and buttressed.

It was technically possible to entrap creatures by casting this spell, but it only worked on creatures with slow reflexes.

A wall of stone could be destroyed by completely mundane means or by means of a disintegrate spell.

Components
The spell required verbal, somatic and material components. The material needed was a small block of granite.

History
The spell was attributed to Netherese arcanist Mavin in -641 DR and was originally called Mavin's stonewall.
