Wooden Horse Necklace

The Wooden Horse Necklace is an amulet that gives the wearer a +2 bonus to armor class and saving throws.

It appears in Baldur's Gate II: Enhanced Edition. It is given by Mereth to the protagonist in the wild mage camp as a reward if you return her the hairband she has lost in Athkatla.
