Bell of Open Lock (鍵解除の鐘) is a magic items that can open locked doors.


An enchanted bell that is part of a three-item bell set.


A rectangular cube-shaped handbell that possesses distinct markings carved on its surface. Upon closer inspection, it has red designs etched upon its bronze surface.


Bell of Open Lock can magically open locked doors. The lock will glow a faint red if not purple light, indicating that the lock's mechanism has been disabled.

This is especially useful when a mechanism is used to keep the door locked as it will instantly unlock with its magic effect. However, this range of effects only works on normal locks. Magically fortified doors are more likely to deny its influence.[1]

Nevertheless, it does not require magic from the user to be activated and is useful for those, depending on the situation, that requires the skills of a thief.


  • Gagaran possesses a number of magical items such as these and gave a set to Climb,[2] who used it during a raid on one of the brothels owned by the Eight Fingers.
