Demolish or Restore Structure

Choose a building, permanent structure, object, or other artificially created feature that you can touch. At the end of the casting time, the object or structure is either restored or demolished, as chosen by the caster. A building cannot be restored to a state that is significantly different than it was when originally built, and the spell will fail unless the majority of the rubble that made up the building or structure is still at the location. Broken materials such as smashed stones or snapped beams are restored to their original form, and the building is restored as though skilled labourers had worked to assemble it form the original materials. Very intricate details, such as a beautiful tapestry or fresco, might not be restored, but instead be replaced with whatever the DM deems to be the best that a general construction labourer could produce in imitation. If the building is demolished, it falls apart into rubble that is small enough to be moved by hand, and that rubble is organized in such a manner as to be as unobtrusive as possible, but is not transported away from the site of the demolition.

The rubble from the demolition does not deal any damage and avoids striking creatures as the structure breaks apart. However, if the demolition has left a building or structure unsound, it may collapse. In this case, any creatures in the spaces where rubble is falling must make a DC 15 dexterity saving throw or take 5d10 bludgeoning damage and be knocked prone, taking half as much damage on a successful save.

Each time the spell is cast, the caster can demolish or restore an amount of a structure not greater than 2 cubic meters (70 cubic feet); this can be neatly divided into 10 linear meters (30 linear feet) of wall that is of a normal thickness, or if it is more convenient for the structure in question, mass can be used instead-- the spell can affect up to 1000 kg (2, 500 lbs) of material (one metric tonne, or a long tonne). If the spell is cast with a spell slot of 4th level or higher, increase the amount of material the spell can affect by 1 cubic meter or 1/2 metric tonne per spell slot level above 3rd.

Concentration is required throughout the duration of the casting time, or the spell fails.

When the spell is cast as a ritual, several extra conditions apply in addition to the normal conditions of ritual spellcasting. when casting Demolish or Restore Structure as a ritual, the casting time is extended to 1 hour instead of by the usual 10 minutes. Additionally, the spell is always cast at the highest available level when cast as a ritual, instead of at the base spell level. So, if a wizard who has 6th level slots available casts this spell as a ritual, it would be considered to have been cast at 6th level, and the spell would be able to affect 5 cubic meters or 2.5 metric tonnes of materials.
