Carver's Rapid Repair

Your body and mind become empowered to rapidly repair objects. When you cast this spell, you can touch one non-magical medium sized object to quickly repair or reinforce. Repairing fixes breaks, fractures, cracks, and even completely shattered objects as the pieces are magically restored to its whole unbroken form. When touching an unbroken object, you can choose to reinforce it adding 4d6 temporary hit points as magical reinforcements strengthen its form. On each of your turns for the duration, you can use your action to repair or reinforce the same object or a different non-magical object. When the spell ends, any repairs or reinforcements disappear.

If you concentrate on this spell for the full duration while choosing to only repair or only reinforce one non-magical object,  the effect becomes permanent.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the temporary hit points of reinforcing an object increase by 2d6 and the size category of objects you can affect increases by one, for each spell slot above 2nd.
