Mending Charm

Undoes damage to an object.

History and Notes

History and notes (BoS3):

• This powerful version of a spell to repair damage was invented by Orabella Nuttley in the mid-1700s.
• The spell will work on most materials, but some are immune to its effects, particularly if damaged by powerful curses.
• It shouldn't be used to try to close wounds on humans or animals, as severe scarring can result.
