|Effects||Opens a lock secured with a Locking Spell|
The Unlocking spell is the counterspell to the defigo Locking Spell.
Unlike the alohomora Unlocking Charm, the effringo incantation may only be used to open a secured lock by the caster of the defigo spell or someone specifically designated by the original caster.
In rare circumstances, however, a person who disarms and takes the wand of the caster can lift the spell using the taken-wand.
Effringo (Latin): "to break, break open"
