You touch a construct or inanimate object, causing it to regain 10d6 hit points. This causes any parts or material that has broken away from the construct or object to reattach, repairing it to the condition it was in before losing those hit points.
If the construct or object's damaged state is the result of age, you can instead repair to the condition it was in 10d6 years ago, if it was previously in a better condition during that time (the condition can only improve or not change).
