The Ring of Human Influence gives the wearer a Charisma of 18, whether this does increase or decrease the score of the character. The Charisma bonus is stackable with other items which increase charisma, such as Helm of the Noble and Plate of Balduran. Also, this ring can be used once per day to cast Charm Person. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. It's dropped by Kalah when he is killed at the end of Investigate the Circus Tent.
