The Object Repairing Spell is a Restoration Magic spell that repairs a broken object. Can be used in conjunction with a magic powder to improve its effectiveness.
Professor Ursula teaches this spell to Akko for her Basic White Magic exam.
Akko tries to use this spell to repair the tombstones that she and Lotte had collapsed. However, by accidentally mixing the powder with Sucy's Grave Mushroom, the spell ends up reviving the corpse of a dead man.
At the end of the episode, Akko use the spell again in the bell of the bell tower whose clapper had been removed to make the stick of the principal Holbrook. Thus, the bell detaches and flies to Luna Nova Academy to gather the part that had been removed.
