Fabricate is vague about what "raw materials" are, and I've concocted multiple scenarios that seem way overpowered for a 4th-level spell. The seemingly overpowered uses are as follows:
- As the spell has no clause about the created object being on a strong surface, you can drop hunks of stone (or anvils) on creatures and buildings, dealing up to 12d6 bludgeoning damage to creatures and/or objects underneath them, requiring only the element of surprise (and sufficient materials).
- A passwall that can be used to bore a 20 ft. deep hole through wood walls or 5 ft. deep through stone or other materials that a) can stack and b) is permanent until filled back in.
Are these uses overpowered compared to other spells of this level, given the 10 minute casting time?
Casting Time: 10 minutes
Range: 120 feet
Components: V, S
You convert raw materials into products of the same material. For example, you can fabricate a wooden bridge from a clump of trees, a rope from a patch of hemp, and clothes from flax or wool.
Choose raw materials that you can see within range. You can fabricate a Large or smaller object (contained within a 10-foot cube, or eight connected 5-foot cubes), given a sufficient quantity of raw material. If you are working with metal, stone, or another mineral substance, however, the fabricated object can be no larger than Medium (contained within a single 5-foot cube). The quality of objects made by the spell is commensurate with the quality of the raw materials.
Creatures or magic items can’t be created or transmuted by this spell. You also can’t use it to create items that ordinarily require a high degree of craftsmanship, such as jewelry, weapons, glass, or armor, unless you have proficiency with the type of artisan’s tools used to craft such objects.
