Mayala's Spider-Charm Necklace
This metal trinket is normally worn on a chain or in a pouch tied around the neck, occupying the same space as a necklace. It bears the symbol of a noble house from a particular drow city and requires a secret command word to activate. Each family’s insignia is slightly different, even those from the same noble house, but each contains a single minor magical ability that can be used once per day.
The necklace of House Baenre enables its wearer to cast the magical ability Spider Climb once per day.
