Eye of Tyr is a pommel gem that can be used to upgrade a weapon of virtue. As the gem is unique, it can be used by Cespenar to upgrade either Carsomyr or the Purifier. This item appears in Baldur's Gate II: Throne of Bhaal and Baldur's Gate II: Enhanced Edition. When taking this gem to Cespenar, it's important to remember that if you have both swords in your inventory, he will upgrade The Purifier. Therefore, if you wish to upgrade Carsomyr, you will need to remove The Purifier from your inventory before speaking to him.
