Amulet of Seldarine

Amulet of Seldarine provides the wearer 10% magic resistance and offers a bonus of -1 to saving throws. This item is gained as a reward for saving Suldanessellar from Jon Irenicus's wrath. The item is gained at the end of Baldur's Gate II: Shadows of Amn, which means the player can actually start using this item from the start Throne of Bhaal. This item also appears in Baldur's Gate II: Enhanced Edition.
