Mending Charm

"The Mending Charm will repair broken objects with a flick of the wand. Accidents do happen, so it is essential to know how to mend our errors."

- An excerpt from the entry in Book of Spells.

The Mending Charm, also known as the Repairing Charm (incantation: Reparo) was a charm that could be used to seamlessly repair a broken object.

Casting and effects
The Mending Charm was effective at repairing most materials. However, damage caused by certain rare, powerful curses was impossible to undo.

The charm was suitable for use only on inanimate objects. Use on living beings was entirely proscribed. Serious scarring could result if it were cast on a person or animal in an attempt to heal wounds.

While a properly cast Mending Charm was generally enough to fix an object, it seems less experienced casters might not succeed in returning liquids to broken containers.

This charm does not seem to work on objects of powerful and complex magic, such as Vanishing Cabinets and wands. Draco Malfoy proved the former by having spent almost an entire school year to repair the damaged cabinet through other means, due to the complexity of the magical passage. For snapped wands, although this charm can repair the physical form, the magical capacity would be damaged beyond repair, causing the wand in question to fall apart once again; the sole exception goes to the Elder Wand, due to the strength.

Invention
This charm was invented by Orabella Nuttley, an employee of the Improper Use of Magic Office in the British Ministry of Magic, in or before 1754. She used her charm to repair the Colosseum after it had been accidentally destroyed. Thereafter, it became famous; this instance was recorded in Book of Spells, by Miranda Goshawk.

Teaching
There are various textbooks containing instructions for this spell, including The Standard Book of Spells, Grade 1, although there is still a spellbook designated entirely to the teaching of this charm. Due to its being a level one spell, it is likely taught in the first year.
